Product details
Overview
HMC231G7 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC SPST switch operating from DC to 6 GHz, delivering 2.0 dB typical insertion loss at 6 GHz, >42 dB isolation up to 6 GHz, and non-reflective 50 Ω termination in OFF state-used in microwave radio front-ends requiring high RF isolation and fast switching.
For engineers reviewing the HMC231G7 datasheet, HMC231G7 pinout, HMC231G7 application, or HMC231G7 equivalent, key selection criteria include its -5/0 V complementary control logic, hermetic SMT package, 3 ns rise/fall time, +27 dBm P1dB, and suitability for space-constrained RF signal routing in telecom and defense systems.
Technical Context
The HMC231G7 implements a non-reflective GaAs MESFET architecture with dual negative-control inputs (A/B) enabling SPST operation via complementary logic: A=High/B=Low activates RF1→RF2 path; A=Low/B=High terminates both ports in 50 Ω. No external bias supply is required.
It supports DC–6 GHz operation with specified performance across temperature (–40°C to +85°C), features Class 1A ESD sensitivity, and requires all ground leads and paddle soldered to PCB RF ground per thick-film alumina package mechanical specs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | DC to 6 GHz - enables broadband RF signal routing without band-switching. |
| Insertion Loss | 2.0 dB typical @ 6 GHz - ensures minimal RF power loss in active path. |
| Isolation | 42 dB @ 6 GHz - suppresses leakage between RF1 and RF2 in OFF state. |
| P1dB | +27 dBm @ 0.5–6 GHz - defines maximum linear input power before 1 dB compression. |
| Switching Speed | 3 ns tRISE/tFALL - supports high-speed TDD and pulse-modulated RF systems. |
| Control Logic | –5 V / 0 V complementary - eliminates need for level shifters or positive supply rails. |
| Return Loss (ON) | 12 dB @ 6 GHz - maintains impedance match under active conduction. |
Pinout & Package
Hermetic surface-mount package with white alumina (92%) body, tungsten thick-film traces, Kovar™ leads/base/cover, and 50 µin gold over nickel plating. Dimensions per outline drawing; all ground leads and bottom paddle must be soldered to PCB RF ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3 | RF2, RF1 | DC-coupled 50 Ω RF ports; require blocking capacitors if DC bias ≠ 0 V. |
| 2, 4, 7 | GND | RF ground terminals; must be soldered to PCB ground plane for return path integrity. |
| 5 | A | Negative control input; High = –5 V, Low = 0 V - determines switch state per truth table. |
| 6 | B | Negative control input; complementary to A - enables non-reflective OFF-state termination. |
Key Features
| Feature | Design Value |
|---|---|
| Non-reflective OFF state | Both RF1 and RF2 terminated in 50 Ω - prevents signal reflections during isolation, critical for VSWR-sensitive systems. |
| Hermetic SMT package | Alumina-based, gold-plated Kovar™ construction - ensures long-term reliability in harsh environments including space and military platforms. |
| No external bias required | Operates solely from –5 V / 0 V control lines - simplifies power architecture and reduces BOM count. |
| Fast switching | 3 ns rise/fall time - supports high-duty-cycle TDD protocols and pulsed radar waveforms. |
| High linearity | +49 dBm IP3 (two-tone, +7 dBm/tone) - preserves signal fidelity in multi-carrier and wideband receiver front-ends. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST RF switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC547LP3E | Wider bandwidth (DC–13 GHz), higher P1dB (+30 dBm), same –5/0 V logic but 3× larger QFN package. | Preferred for Ka-band systems; less suitable for space-constrained 6 GHz designs. | Select when extending beyond 6 GHz or requiring higher power handling. |
| Qorvo QM11036 | Si-based, 0.1–6 GHz range, +5 V control, 2.5 dB IL @ 6 GHz, lower isolation (38 dB). | Cost-optimized for commercial infrastructure; lacks hermeticity and military temp range. | Choose for non-mission-critical, cost-sensitive 5G small cells where ESD robustness is secondary. |
Compared with HMC547LP3E and QM11036, the HMC231G7 uniquely balances hermetic reliability, –5/0 V simplicity, and 42 dB isolation at 6 GHz in a compact SMT footprint-making it optimal for SWaP-constrained defense and space-grade RF front-ends.

FAQ
What is the operating temperature range for the HMC231G7?
The HMC231G7 operates from –40°C to +85°C and is rated for storage between –65°C and +150°C. Its thermal resistance (junction-to-lead) is 94°C/W, and channel temperature must not exceed 150°C. These ratings are validated per absolute maximum specifications in the official datasheet revision v02.1006.
Does the HMC231G7 require an external bias supply?
No, the HMC231G7 requires no external bias supply. It operates using only complementary –5 V and 0 V control voltages applied to pins A and B. This eliminates the need for dedicated bias rails, simplifying system-level power design and reducing component count around the HMC231G7.
What is the recommended PCB grounding practice for the HMC231G7?
All ground pins (2, 4, 7) and the exposed ground paddle on the HMC231G7 package bottom must be soldered directly to the PCB RF ground plane. This ensures low-inductance return paths, preserves RF performance, and meets the mechanical specification requiring full paddle soldering per thick-film alumina package guidelines.
Can the HMC231G7 handle high RF input power?
Yes-the HMC231G7 supports +30 dBm RF input power at +50°C (absolute max), with +27 dBm P1dB and +49 dBm IP3 under standard test conditions. However, "hot switching" above +27 dBm is cautioned against per datasheet note, as it may accelerate degradation of the GaAs MESFET structure in the HMC231G7.
Is the HMC231G7 still in production or obsolete?
The HMC231G7 is marked "OBSOLETE" in its official datasheet (v02.1006), indicating end-of-life status by Analog Devices. However, Aetrix Electronics maintains legacy inventory and offers lifecycle availability coordination, traceable sourcing, and obsolescence mitigation support for ongoing production programs using the HMC231G7.
