Product details
Overview
ADG901SCPZ-EP-RL7 from Analog Devices is a military-grade, absorptive SPST RF switch fabricated in CMOS process, delivering 38 dB off-isolation at 1 GHz, 0.8 dB insertion loss at 1 GHz, and −3 dB bandwidth up to 4.5 GHz. It operates from 1.65 V to 2.75 V, features CMOS/LVTTL-compatible control logic, and is deployed in antenna diversity switching and digital transceiver front-end signal routing.
For engineers reviewing the ADG901SCPZ-EP-RL7 datasheet, ADG901SCPZ-EP-RL7 pinout, ADG901SCPZ-EP-RL7 application, or ADG901SCPZ-EP-RL7 equivalent, this page provides verified electrical specs, military-temperature performance data, LFCSP package layout, and validated alternatives for defense/aerospace RF subsystem design.
Technical Context
The ADG901SCPZ-EP-RL7 implements an absorptive (50 Ω-terminated shunt-leg) topology with on-board CMOS control logic, eliminating external level-shifting circuitry. Its RF path supports dc–4.5 GHz operation while maintaining matched impedance across both on and off states.
It achieves sub-10 ns switching times (tON = 6.5 ns typ, tOFF = 10.5 ns typ) and delivers high linearity with IP3 = 36 dBm at 900 MHz and P1dB = 17 dBm at 1 GHz - critical for wideband wireless front ends operating under MIL-STD temperature extremes (−55°C to +125°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 4.5 GHz - enables full coverage of UHF, L-, S-, and lower C-band RF signals without roll-off. |
| Off Isolation @ 1 GHz | 38 dB - suppresses crosstalk between antenna paths in diversity systems. |
| Insertion Loss @ 1 GHz | 0.8 dB - minimizes signal attenuation in active RF signal routing paths. |
| Supply Voltage Range | 1.65 V to 2.75 V - compatible with low-voltage FPGA/CPU I/O domains and battery-powered radios. |
| Switching Time (tON) | 6.5 ns typical - supports fast time-division duplex (TDD) and dynamic filter bank reconfiguration. |
| IP3 @ 900 MHz | 36 dBm - ensures minimal intermodulation distortion in multi-carrier LTE/5G front ends. |
| P1dB @ 1 GHz | 17 dBm - defines maximum linear input power before 1 dB gain compression occurs. |
| Operating Temperature | −55°C to +125°C - qualified per AQEC standard for sustained operation in aerospace avionics and radar modules. |
Pinout & Package
ADG901SCPZ-EP-RL7 uses an 8-lead Lead Frame Chip Scale Package (LFCSP), 3 mm × 3 mm body, 0.75 mm height, with exposed thermal pad requiring connection to PCB ground plane for optimal RF performance and thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Positive supply input | Accepts 1.65 V–2.75 V; must be decoupled to GND with 0.1 µF capacitor near pin. |
| 2 (CTRL) | Digital control input | CMOS/LVTTL-compatible; logic high connects RF1–RF2, logic low isolates them. |
| 3, 5, 6, 7 (GND) | Ground reference | Four dedicated GND pins ensure low-inductance return path for RF and digital currents. |
| 4 (RF1) | RF input port | 50 Ω matched input; connects to source (e.g., PA output or antenna feed). |
| 8 (RF2) | RF output port | 50 Ω matched output; routes signal to LNA, filter bank, or second antenna. |
| EPAD | Exposed thermal pad | Must be soldered to solid GND plane; improves thermal resistance (θJA = 48°C/W) and RF stability. |
Key Features
| Feature | Design Value |
|---|---|
| Absorptive architecture | 50 Ω-terminated shunt legs prevent reflected energy during off-state, enabling stable VSWR < 1.5:1 across band. |
| Ultra-low quiescent current | <2.5 µA IDD - extends battery life in portable SATCOM terminals and UAV telemetry radios. |
| Military qualification support | AQEC-compliant baseline with single fab/test site, controlled change notification, and full qualification data on request. |
| High-speed switching | tRISE = 5.5 ns max, tFALL = 9.5 ns max - enables precise timing alignment in TDD-based phased arrays. |
| Video feedthrough suppression | 2.5 mVp-p - prevents control-line transients from coupling into sensitive RF receive paths. |
Applications
| Antenna Diversity Switching | Dual-Band Transceiver Front End |
|---|---|
|
Use Scenario: Selecting between two physically separated antennas in mobile satellite terminals to mitigate fading. IC Role / Device Role / Timing Role: Absorptive SPST switch routing RF between primary and diversity antenna ports under real-time RSSI control. Use Value: 38 dB isolation at 1 GHz prevents desensitization of the active receiver path by leakage from the inactive antenna. |
Use Scenario: Sharing a single RF front end between L-band (1.5 GHz) and S-band (2.5 GHz) receive chains in tactical radios. IC Role / Device Role / Timing Role: High-linearity RF path selector enabling rapid band switching without external bias networks. Use Value: 4.5 GHz −3 dB bandwidth and 17 dBm P1dB allow clean signal routing across both bands without compression or harmonic generation. |
| IF Signal Routing in Radar Modules | Tuner Module Switching |
|
Use Scenario: Dynamically connecting IF outputs from multiple ADC channels to a shared digital downconverter in AESA radar receivers. IC Role / Device Role / Timing Role: Low-insertion-loss (0.8 dB), fast-switching (6.5 ns tON) gate for time-sliced IF sampling. Use Value: Sub-10 ns switching enables precise time-domain multiplexing of IF streams without inter-channel skew or amplitude droop. |
Use Scenario: Selecting between multiple RF filter banks in broadcast TV tuners supporting ATSC 3.0 and DVB-T2 standards. IC Role / Device Role / Timing Role: Wideband absorptive switch isolating unused filter paths to maintain system noise figure and image rejection. Use Value: 20 dB return loss (on-channel) and 19 dB (off-channel) at 1 GHz preserve tuner impedance match and minimize passband ripple. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar RF switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC646LP2E | Higher supply voltage (3 V–5.5 V); 42 dB isolation @ 1 GHz; GaAs pHEMT process. | Better power handling (P1dB = 27 dBm) but lacks military temp range (−40°C to +85°C only). | Select when higher RF power tolerance is required and extended temperature is not mandated. |
| ADGM1304 | MEMS-based SP4T switch; 0.3 dB insertion loss; 45 dB isolation @ 1 GHz; requires external driver. | Superior linearity (IP3 = 55 dBm) and zero DC power, but slower switching (10 µs) and no AQEC qualification. | Select for ultra-low distortion receive-only paths where speed and military spec are secondary. |
Compared with HMC646LP2E and ADGM1304, the ADG901SCPZ-EP-RL7 uniquely balances military-temperature operation, sub-10 ns switching, and CMOS-level supply compatibility - making it the only choice for SWaP-constrained defense radios requiring both speed and ruggedness.

FAQ
What is the operating temperature range of the ADG901SCPZ-EP-RL7?
The ADG901SCPZ-EP-RL7 is rated for continuous operation from −55°C to +125°C, fully qualified per AQEC standards for defense and aerospace applications. This extended range is enabled by controlled manufacturing baseline, single fabrication site, and enhanced product change notification - all documented in the ADG901-EP Rev. A datasheet.
Does the ADG901SCPZ-EP-RL7 require external biasing or matching components?
No, the ADG901SCPZ-EP-RL7 integrates on-chip 50 Ω termination for its absorptive architecture and requires only a 0.1 µF decoupling capacitor on VDD. Its RF ports are internally matched to 50 Ω across dc–4.5 GHz, eliminating external baluns, bias tees, or matching networks in most L/S-band implementations.
How does the ADG901SCPZ-EP-RL7 differ from commercial-grade ADG901 variants?
The ADG901SCPZ-EP-RL7 differs from commercial ADG901 versions through military-grade screening: extended temperature testing (−55°C to +125°C), controlled manufacturing baseline, single assembly/test site, enhanced product change notification, and full AQEC compliance documentation. Electrical specs remain identical, but reliability and traceability are elevated for mission-critical use.
Can the ADG901SCPZ-EP-RL7 be used in transmit paths with high RF power?
The ADG901SCPZ-EP-RL7 supports 17 dBm P1dB at 1 GHz and handles 18 dBm peak input power per Absolute Maximum Ratings. For continuous transmit operation above 10 dBm, thermal derating per Table 2 is required - e.g., max 2.8 mA channel current at +125°C limits average power in high-duty-cycle PA switching applications.
What is the function of the exposed pad (EPAD) on the ADG901SCPZ-EP-RL7 LFCSP package?
The exposed pad on the ADG901SCPZ-EP-RL7 must be soldered to a solid PCB ground plane. It serves dual roles: (1) thermal conduction path reducing θJA to 48°C/W, and (2) RF reference node stabilizing impedance and minimizing ground bounce during fast switching - both essential for maintaining 38 dB isolation and 0.8 dB insertion loss at 1 GHz.
