Product details
Overview
ADG936BRU-R from Analog Devices is a reflective dual SPDT RF switch optimized for high-isolation, low-loss signal routing in wireless front ends. It operates from DC to 4 GHz (−3 dB), delivers 36 dB off-isolation at 1 GHz, 0.9 dB insertion loss at 1 GHz, and runs on a single 1.65 V to 2.75 V CMOS supply - enabling antenna diversity switching in compact 5G handsets and ISM-band transceivers.
For engineers reviewing the ADG936BRU-R datasheet, ADG936BRU-R pinout, ADG936BRU-R application, or ADG936BRU-R equivalent, key selection criteria include its reflective architecture (vs. absorptive ADG936), 20-lead TSSOP package compatibility, RF port crosstalk ≤37 dB at 1 GHz, and guaranteed −40°C to +85°C industrial operation without external biasing or DC blocking capacitors.
Technical Context
The ADG936BRU-R implements two independent SPDT switches with reflective termination (0 Ω shunt to GND), resulting in high off-isolation but degraded off-port VSWR compared to absorptive variants. Its on-board CMOS/LVTTL-compatible control logic eliminates external level-shifting circuitry.
It achieves 11 ns typical turn-on time and 10 ns turn-off time with 6.1 ns rise/fall times, supporting high-speed filter selection and Tx/Rx path switching up to 1 GHz. The device maintains 16 dBm input power handling and 27.5 dBm IP3 at 900 MHz under 2.5 V supply and 25°C conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | DC to 4 GHz (−3 dB bandwidth); supports full ISM band (2.4 GHz/5.8 GHz) and sub-6 GHz 5G FR1 front-end routing. |
| Off Isolation @ 1 GHz | 36 dB typical; ensures ≥31 dB minimum isolation between RFCx and RF1x/RF2x ports, critical for Tx/Rx signal separation. |
| Insertion Loss @ 1 GHz | 0.9 dB typical; enables minimal signal attenuation in active paths, preserving SNR in LNA/PA interfaces. |
| Supply Voltage Range | 1.65 V to 2.75 V; compatible with modern low-voltage SoC I/O domains and battery-powered IoT devices. |
| Switching Time (tON) | 11 ns typical; supports fast reconfiguration in time-division duplex (TDD) systems and dynamic filter banks. |
| Input Power Handling | 16 dBm @ 1 GHz; sufficient for direct integration after PA output or before LNA input without external attenuation. |
| Third-Order Intercept (IP3) | 27.5 dBm typical @ 900 MHz; indicates low intermodulation distortion in multi-carrier LTE/Wi-Fi coexistence scenarios. |
Pinout & Package
ADG936BRU-R is housed in a 20-lead Thin Shrink Small Outline Package (TSSOP, RU-20), 6.5 mm × 4.4 mm body, 0.65 mm pitch, with exposed pad tied to GND for thermal and RF grounding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA, INB | Digital control inputs | CMOS/LVTTL-compatible logic pins; drive internal switch matrix; high = connect RFCx to RF1x, low = connect RFCx to RF2x (per truth table). |
| RFCA, RFCB | Common RF ports (Switch A/B) | Primary RF signal entry points; each connects to either RF1x or RF2x based on corresponding INx state. |
| RF1A, RF2A, RF1B, RF2B | RF switch legs | Terminated reflectively (0 Ω to GND); used for antenna diversity, filter bank selection, or Tx/Rx path routing. |
| VDD | Power supply | Single 1.65–2.75 V rail; requires local 10 µF decoupling to GND per datasheet layout guidance. |
| GND (11 pins) | Ground reference | Multiple dedicated ground pins minimize return path inductance; exposed pad must be soldered to PCB ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Reflective dual SPDT architecture | Enables high off-isolation without 50 Ω shunt resistors, reducing die area and power dissipation vs. absorptive ADG936. |
| No DC blocking capacitors required | Allows direct coupling of DC-biased RF signals (e.g., PA output, LNA input), simplifying BOM and board layout. |
| 1 µA max quiescent current | Supports always-on antenna switching in battery-constrained IoT sensors and wearable radios. |
| 20-lead TSSOP and LFCSP options | TSSOP (RU-20) provides legacy compatibility; LFCSP (CP-20-6) offers 4 mm × 4 mm footprint for space-constrained modules. |
| Industrial temperature range | Specified from −40°C to +85°C; validated for automotive infotainment tuners and industrial wireless gateways. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG936BRUZ | Absorptive dual SPDT with 50 Ω terminated shunt legs; 24 dB return loss on off-port vs. reflective ADG936BRU-R's <16 dB. | Required where stable VSWR into off-port is critical (e.g., sensitive receiver front ends with poor impedance tolerance). | Select ADG936BRUZ when minimizing reflections back to source is prioritized over power efficiency or die size. |
| Qorvo QM11036 | Single-pole double-throw (SPDT), not dual; 0.5 dB lower insertion loss (0.4 dB @ 1 GHz), but no second independent switch channel. | Suitable only for single-path switching; lacks concurrent dual-band or Tx+Rx routing capability of ADG936BRU-R. | Choose QM11036 for cost-sensitive, single-switch applications where dual SPDT functionality is unnecessary. |
Compared with ADG936BRUZ, ADG936BRU-R trades off-port matching for lower power and smaller die; versus QM11036, it provides two independent SPDTs in one package-enabling simultaneous Tx/Rx and antenna diversity control without stacking devices.

FAQ
What is the key functional difference between ADG936BRU-R and ADG936BRU?
The ADG936BRU-R is a reflective dual SPDT switch with 0 Ω shunt-to-ground termination, while ADG936BRU is absorptive with 50 Ω matched shunt legs. This makes ADG936BRU-R better suited for applications where off-port VSWR is not critical but power efficiency and die size matter - such as antenna diversity in mobile handsets. ADG936BRU-R maintains identical pinout, supply, and control interface with ADG936BRU.
Does ADG936BRU-R require external DC blocking capacitors?
No, ADG936BRU-R does not require external DC blocking capacitors. Its RF ports are internally DC-coupled and rated for continuous DC bias, enabling direct connection to PA outputs or LNA inputs without signal path interruption. This simplifies layout and reduces BOM count compared to AC-coupled alternatives.
What is the maximum RF input power ADG936BRU-R can handle?
ADG936BRU-R supports up to 16 dBm input power at 1 GHz (P−1dB = 16 dBm), with 18 dBm absolute maximum rating. At 900 MHz, third-order intercept is 27.5 dBm, confirming robust linearity for multi-carrier LTE/Wi-Fi signals. Operation above 16 dBm risks compression-induced distortion and should be avoided in linear signal paths.
Which package does ADG936BRU-R use, and is it RoHS-compliant?
ADG936BRU-R uses the 20-lead TSSOP package (RU-20), measuring 6.5 mm × 4.4 mm with 0.65 mm pitch and an exposed thermal pad. It is RoHS-compliant and lead-free, as confirmed by the "Z" suffix absence in the ordering code - unlike ADG936BRUZ-R which carries the Z designation. Full compliance documentation is available upon request.
Can ADG936BRU-R operate from a 1.8 V supply in battery-powered designs?
Yes, ADG936BRU-R is fully specified from 1.65 V to 2.75 V, including 1.8 V nominal supply. At 1.8 V, insertion loss remains ≤1.25 dB at 1 GHz and off-isolation stays ≥31 dB, meeting requirements for ultra-low-power IoT radios and wearable transceivers. Quiescent current stays below 1 µA across the full voltage range.
