Product details
Overview
HMC641ATCPZ-EP-RL7 from Analog Devices is a GaAs-based nonreflective SP4T RF switch operating from 0.1 GHz to 20 GHz, featuring 3.0 dB max insertion loss and 40 dB isolation at 20 GHz, with integrated 2-to-4 decoder and −5 V supply operation for military-grade microwave signal routing in radar front-ends.
For engineers reviewing the HMC641ATCPZ-EP-RL7 datasheet, HMC641ATCPZ-EP-RL7 pinout, HMC641ATCPZ-EP-RL7 application, or HMC641ATCPZ-EP-RL7 equivalent, key selection criteria include broadband isolation performance across 20 GHz, negative logic control compatibility, ESD-hardened Class 1A rating, and qualification for −55°C to +125°C operation in defense electronics.
Technical Context
The HMC641ATCPZ-EP-RL7 implements a nonreflective 50 Ω architecture with on-chip terminations for all off-state ports, enabling stable impedance matching during switching transients. Its GaAs process delivers high linearity (P1dB = 24 dBm, IP3 = 41 dBm) and power handling (26.5 dBm through path) under −5 V bias.
Control is managed via two negative logic inputs (CTRLA/CTRLB) driving an integrated binary 2-to-4 decoder, eliminating external logic. Switching speed is characterized by 30 ns rise/fall time and 100 ns on/off time, supporting fast TDD and beam-steering applications.
Key Specifications

|---|---|
| Frequency Range | 0.1 GHz to 20 GHz - supports full microwave band coverage including L-, S-, C-, X-, Ku-, and K-bands. |
| Insertion Loss | 3.0 dB max (12–20 GHz) - ensures minimal RF signal attenuation in active paths for high-fidelity signal routing. |
| Isolation | 40 dB min (12–20 GHz) - prevents crosstalk between selected and terminated RF ports in multi-path systems. |
| P1dB | 24 dBm typical at VSS = −5 V - enables handling of high-power transmit signals without compression in radar pulse applications. |
| IP3 | 41 dBm typical - maintains signal integrity in dense spectral environments like VSAT uplinks and ECM jammers. |
| Supply Voltage | −5 V to −3 V - compatible with standard negative rail supplies in legacy military avionics and test instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SP4T RF switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC641ALP4E | Same die, 24-lead QFN (4 mm × 4 mm), commercial temp range (−40°C to +85°C), no AQEC qualification. | Lacks military temperature rating and enhanced product change notification; suitable for lab/test equipment but not flight hardware. | Select HMC641ALP4E only for cost-sensitive commercial designs where extended temperature and traceability are not required. |
| Qorvo QM11036 | Si-based SP4T, 0.05–6 GHz range, 0.9 dB IL @ 3.5 GHz, 32 dB isolation @ 3.5 GHz, +3.3 V supply. | Lower frequency limit and narrower bandwidth; optimized for sub-6 GHz 5G, not Ka-band or radar. | Choose QM11036 for cellular infrastructure where GaAs performance is unnecessary and positive supply simplifies power design. |

FAQ
What is the operating temperature range of the HMC641ATCPZ-EP-RL7?
The HMC641ATCPZ-EP-RL7 is qualified for continuous operation from −55°C to +125°C case temperature, meeting AQEC standards for defense and aerospace applications. This extended range is enabled by controlled manufacturing baseline, single fabrication/assembly site, and enhanced product change notification-ensuring reliability in airborne, ground vehicle, and space-constrained environments where thermal cycling is severe.
Does the HMC641ATCPZ-EP-RL7 require external termination resistors?
No, the HMC641ATCPZ-EP-RL7 does not require external termination resistors. It features an integrated nonreflective architecture with on-chip 50 Ω terminations for all four RF output ports (RF1–RF4) when those paths are in the off state. This eliminates reflected energy and maintains system VSWR stability without adding discrete components or layout complexity-critical for high-frequency PCB designs where parasitic effects dominate.
What supply voltage and logic levels are compatible with the HMC641ATCPZ-EP-RL7 control inputs?
The HMC641ATCPZ-EP-RL7 operates with a negative supply voltage (VSS) of −5 V or −3 V and accepts negative logic control inputs: CTRLA and CTRLB accept 0 V (high) and VSS (low), with specified VINL/VINH thresholds (e.g., −5 V to −4.2 V for high at VSS = −5 V). This eliminates need for level shifters when interfacing with FPGA or ASIC outputs that support dual-rail or open-drain negative logic configurations.
How does the HMC641ATCPZ-EP-RL7 differ from the commercial-grade HMC641ALP4E?
The HMC641ATCPZ-EP-RL7 shares the same GaAs die and RF performance as the HMC641ALP4E but adds military-grade enhancements: AQEC qualification, −55°C to +125°C temperature rating, controlled manufacturing baseline, single assembly/fabrication site, and enhanced product change notification. These make the HMC641ATCPZ-EP-RL7 suitable for flight-critical and long-lifecycle defense programs where traceability and environmental resilience are mandated.
Can the HMC641ATCPZ-EP-RL7 be used in hot-switching configurations?
Yes, the HMC641ATCPZ-EP-RL7 supports hot switching with a maximum RF input power of 20 dBm under hot-switch conditions (VSS = −5 V), as specified in its Absolute Maximum Ratings table. This capability enables dynamic reconfiguration of RF paths while powered-essential for adaptive radar modes, frequency-hopping spread spectrum, and real-time test system reprogramming without interrupting DC bias or cooling cycles.
