Product details
Overview
ADG936BRU-500RL7 from Analog Devices is an absorptive dual SPDT RF switch optimized for wideband operation up to 4 GHz, delivering 36 dB off-isolation at 1 GHz, 0.9 dB insertion loss at 1 GHz, and CMOS/LVTTL-compatible control with 1.65 V to 2.75 V supply. It serves as a matched RF signal routing element in antenna diversity and transceiver front-end architectures.
For engineers reviewing the ADG936BRU-500RL7 datasheet, ADG936BRU-500RL7 pinout, ADG936BRU-500RL7 application, or ADG936BRU-500RL7 equivalent, key selection criteria include absorptive port termination (50 Ω shunt), TSSOP-20 package compatibility, high-frequency isolation performance, and low-power 1 μA quiescent current in wireless infrastructure and portable RF designs.
Technical Context
The ADG936BRU-500RL7 implements two independent absorptive SPDT switches using a CMOS process, each with 50 Ω terminated shunt legs to ensure stable VSWR across RF ports regardless of switch state. Its on-board CMOS control logic accepts direct CMOS/LVTTL inputs without level-shifting circuitry.
It operates over −40°C to +85°C with 1.65 V–2.75 V single-supply biasing, supports 0 dBm input power up to 1 GHz, and achieves 11 ns typical on-switching time and 6.1 ns rise time - enabling use in fast-settling RF signal paths such as Tx/Rx switching and IF multiplexing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | DC to 4 GHz (−3 dB bandwidth); enables full ISM band coverage including 2.4 GHz and 5 GHz Wi-Fi bands without external matching. |
| Off Isolation @ 1 GHz | 36 dB typical; ensures >99% RF signal attenuation between RFCx and RF1x/RF2x ports during off-state, critical for Tx/Rx isolation. |
| Insertion Loss @ 1 GHz | 0.9 dB typical; minimizes signal degradation in active signal paths, preserving SNR in receiver front ends and filter selection networks. |
| Supply Voltage Range | 1.65 V to 2.75 V; compatible with modern low-voltage SoC I/O domains and battery-powered RF modules. |
| Quiescent Current | 1 μA maximum; eliminates standby power concerns in always-on antenna diversity or IoT sensor node applications. |
| Switching Time (tON) | 11 ns typical; supports rapid reconfiguration in time-division duplex (TDD) systems and agile frequency-hopping receivers. |
| Package | 20-lead TSSOP (RU-20); industry-standard footprint with 0.65 mm pitch, suitable for compact RF PCB layouts requiring thermal and EMI control. |
Pinout & Package
ADG936BRU-500RL7 is housed in a 20-lead Thin Shrink Small Outline Package (TSSOP, RU-20) with exposed pad tied to GND for thermal and RF grounding. Pin 1 is marked by a dot; the exposed pad must be soldered to a solid ground plane per Analog Devices' layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA, INB | Logic Control Inputs | CMOS/LVTTL-compatible digital inputs controlling SPDT A and B independently; logic high selects RF1x path, low selects RF2x path (per truth table). |
| RFCA, RFCB | Common RF Ports | Matched 50 Ω input/output ports for Switch A and B; internally terminated to 50 Ω in off-state for absorptive behavior and stable VSWR. |
| RF1A, RF2A, RF1B, RF2B | RF Switch Terminals | 50 Ω-terminated RF paths; RF1x connects to common port when INA/INB = high; RF2x connects when low - no external DC blocking required. |
| VDD | Power Supply Input | Single 1.65 V–2.75 V supply; requires local 10 µF decoupling to GND to maintain RF performance stability under fast switching transients. |
| GND (Pins 2,3,5,6,8,9,11,13,15,16,18,20) | Ground Reference | Multiple dedicated GND pins minimize ground inductance; all must be connected to low-impedance RF ground plane for optimal isolation and return loss. |
Key Features
| Feature | Design Value |
|---|---|
| 50 Ω absorptive termination | Ensures consistent 16–25 dB return loss across RF ports in both on/off states, eliminating need for external matching networks in 50 Ω systems. |
| Wideband −3 dB bandwidth | Extends to 4 GHz, supporting LTE Band 42/43 (3.4–3.8 GHz), 5G NR n77/n78 (3.3–3.8 GHz), and unlicensed U-NII bands without performance roll-off. |
| Low distortion linearity | IP3 = 32 dBm @ 900 MHz enables clean multi-tone operation in FDD transceivers and concurrent dual-band receivers without intermodulation artifacts. |
| Fast RF switching | tON/tOFF ≤ 14 ns ensures sub-100 ns total reconfiguration time, meeting timing budgets in TDD-based 5G FR1 and Wi-Fi 6E beamforming control loops. |
| No external DC blocking | Internal DC coupling allows baseband and RF signals (including LO leakage) to pass through without series capacitors - reducing BOM count and insertion loss. |
Applications
| Antenna Diversity Switching | Tuner Module Signal Routing |
|---|---|
|
Use Scenario: Selecting among multiple antennas in smartphone or set-top box tuner modules to improve received signal strength and mitigate multipath fading. IC Role / Device Role / Timing Role: Dual SPDT absorptive switch routing RF from antenna array to LNA or tuner IC, with simultaneous control of two independent antenna paths. Use Value: 36 dB isolation prevents cross-coupling between antenna branches; 0.9 dB insertion loss preserves weak signal integrity; 1 μA quiescent current extends battery life in portable tuners. |
Use Scenario: Dynamically selecting between multiple SAW/BAW filters in broadcast or cellular tuner front ends to support multi-band reception (e.g., LTE Bands 1+3+7). IC Role / Device Role / Timing Role: High-speed RF multiplexer enabling filter bank switching within <100 ns, synchronized with channel acquisition timing in digital TV or LTE demodulators. Use Value: 4 GHz bandwidth covers all cellular and broadcast bands up to 3.8 GHz; absorptive architecture avoids reflected energy disrupting upstream filter response. |
| Digital Transceiver Front End | IF Switching in Radar Receivers |
|
Use Scenario: Isolating transmit and receive paths in half-duplex cellular or Wi-Fi transceivers operating in TDD mode, where shared antenna requires precise timing-controlled switching. IC Role / Device Role / Timing Role: Transmit/receive switch placed between PA output and LNA input, controlled by baseband processor GPIOs with nanosecond-level timing alignment. Use Value: 36 dB off-isolation prevents PA output from saturating LNA; 11 ns tON supports tight TDD guard intervals in LTE-TDD and 5G NR TDD configurations. |
Use Scenario: Routing intermediate frequency (IF) signals between multiple ADC channels or filter banks in pulsed radar receivers requiring rapid waveform adaptation. IC Role / Device Role / Timing Role: Low-loss IF signal router operating at 100–500 MHz, switching between analog beamformer outputs and digitization chains during pulse repetition intervals. Use Value: 0.5 dB insertion loss at 500 MHz maintains dynamic range; 47 dB isolation at 500 MHz suppresses crosstalk between parallel IF processing paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT RF switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC646LP4E | Reflective dual SPDT; 0 Ω shunt termination; higher 45 dB isolation @ 1 GHz but degraded VSWR in off-state. | Suitable only where off-port reflections are acceptable (e.g., non-critical filter bypass); not drop-in due to different impedance behavior. | Select HMC646LP4E only if system-level VSWR budget permits reflective mismatch and higher isolation outweighs absorptive benefits. |
| Qorvo QM11025 | Single SPDT; 50 Ω absorptive; 0.7 dB IL @ 2.7 GHz; 32 dB isolation @ 2.7 GHz; 1.8 V–3.6 V supply. | Requires two devices to replicate dual functionality; wider voltage range but lower isolation at 1 GHz vs. ADG936BRU-500RL7. | Choose QM11025 only when dual-channel integration is unnecessary and 2.7 GHz optimization is prioritized over 1 GHz isolation and dual-path consolidation. |
Compared with HMC646LP4E and QM11025, ADG936BRU-500RL7 uniquely delivers dual absorptive SPDT functionality in a single RU-20 package with guaranteed 36 dB isolation and 0.9 dB loss at 1 GHz - making it the only option that satisfies stringent VSWR, integration density, and sub-1 GHz wireless infrastructure requirements without design compromises.

FAQ
What is the RF port configuration of the ADG936BRU-500RL7?
The ADG936BRU-500RL7 integrates two independent absorptive SPDT switches. Each switch has one common RF port (RFCA or RFCB) and two selectable RF paths (RF1x/RF2x). All RF ports are internally 50 Ω matched, enabling direct connection to 50 Ω transmission lines without external DC blocking or matching components. This configuration supports bidirectional RF routing in antenna diversity and filter selection applications.
Does the ADG936BRU-500RL7 require external DC blocking capacitors?
No, the ADG936BRU-500RL7 does not require external DC blocking capacitors. Its RF ports are internally DC-coupled and 50 Ω matched in both on and off states. This eliminates series capacitors from the signal path, reducing insertion loss, board area, and cost - particularly beneficial in space-constrained mobile RF front ends and multi-layer tuner modules where capacitor placement impacts impedance control.
What is the difference between ADG936BRU-500RL7 and ADG936BRU-R-500RL7?
The ADG936BRU-500RL7 is the absorptive version (50 Ω shunt termination), while ADG936BRU-R-500RL7 is the reflective version (0 Ω shunt to ground). The absorptive variant ensures stable VSWR on all ports regardless of switch state, making it suitable for antenna-facing applications where reflected energy must be minimized. The reflective version offers higher isolation but degrades off-port VSWR - limiting its use to non-critical signal paths like internal filter bypass.
Can the ADG936BRU-500RL7 operate from a 1.8 V supply?
Yes, the ADG936BRU-500RL7 operates across 1.65 V to 2.75 V, fully supporting 1.8 V nominal supply rails. At 1.8 V, it maintains 0.9 dB insertion loss at 1 GHz and 31 dB off-isolation (min), with input logic thresholds adjusted to 0.65×VDD (high) and 0.35×VDD (low) - ensuring reliable CMOS/LVTTL compatibility with 1.8 V microcontrollers and baseband processors without level shifters.
Is the ADG936BRU-500RL7 pin-compatible with other ADG9xx variants in TSSOP?
Yes, all ADG936/ADG936-R variants in the 20-lead TSSOP package (RU-20), including ADG936BRU-500RL7, ADG936BRUZ, and ADG936BRU-R-500RL7, share identical pinout, footprint, and thermal pad layout. This allows direct substitution between absorptive and reflective versions during prototyping or revision-controlled production - provided system-level RF performance requirements (e.g., VSWR, isolation) are verified for the selected variant.
