Product details
Overview
HMC232LP4E from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC SPDT non-reflective switch operating from DC to 12 GHz, delivering 1.5 dB typical insertion loss at 6 GHz, >60 dB isolation up to 3 GHz, and +27 dBm input P1dB compression. It uses complementary -5/0 V control logic, requires no external bias supply, and is deployed in microwave radio front-ends and test instrumentation signal routing.
For engineers reviewing the HMC232LP4E datasheet, HMC232LP4E pinout, HMC232LP4E application, or HMC232LP4E equivalent, key selection criteria include its non-reflective architecture, 24-lead 4×4 mm QFN package, DC–12 GHz bandwidth, -40°C to +85°C operating range, and compatibility with high-isolation RF switching in telecom and defense systems.
Technical Context
The HMC232LP4E implements a monolithic GaAs MESFET-based SPDT switch with integrated termination for non-reflective operation in both OFF states, enabling stable impedance matching across DC–12 GHz. Its complementary negative-voltage control (A/B pins at -5 V / 0 V) eliminates need for level-shifting circuitry.
Switching is characterized by 3 ns rise/fall time and 6 ns ON/OFF delay, with thermal resistance of 94 °C/W (junction-to-lead) and ESD rating Class 1A (HBM). The device maintains ≥42 dB isolation up to 12 GHz and supports +30 dBm absolute maximum RF input power at +50 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | DC to 12 GHz - supports broadband RF routing without band-switching hardware |
| Insertion Loss | 1.5 dB typical @ 6 GHz - minimizes signal attenuation in active signal paths |

Pinout & Package
Package: 24-lead, 4 mm × 4 mm, RoHS-compliant QFN with exposed ground paddle; requires soldering all ground leads and paddle to PCB RF ground per Hittite land pattern guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| RF2 (Pin 22) | SPDT output path 2 | DC-coupled 50 Ω output; independently controlled and terminated when inactive |
| A (Pin 16) | Control input A | Accepts -5 V (LOW) or 0 V (HIGH); defines RFC→RF1 path activation per truth table |
| B (Pin 15) | Control input B | Complementary to A; -5 V/0 V logic selects RFC→RF2 path |
| GND (Pins 3,5,8,10,21,23) | RF and DC ground | Must be connected to low-inductance PCB ground plane; package bottom paddle also grounded |
| N/C (Pins 1,2,6,7,11,12,13,14,17,18,19,20,24) | No internal connection | Externally grounded per measurement setup but electrically unused |

FAQ
What is the operating temperature range for the HMC232LP4E?
The HMC232LP4E operates over -40°C to +85°C ambient temperature. This range is validated per Absolute Maximum Ratings and electrical specifications tables in the official datasheet. Thermal resistance is specified as 94 °C/W (junction-to-lead), supporting reliable operation in base station and field-deployed military equipment. Derating applies above +85°C ambient; full performance is guaranteed only within the stated range.
Does the HMC232LP4E require an external bias supply?
No, the HMC232LP4E requires no external bias supply. It operates solely from complementary -5 V / 0 V control voltages applied to pins A and B. All DC biasing is internally generated using GaAs MESFET technology. This eliminates need for dedicated bias rails, simplifying system power architecture and reducing bill-of-materials cost compared to bias-dependent RF switches.
What is the meaning of "non-reflective" in the HMC232LP4E datasheet?
"Non-reflective" means the HMC232LP4E terminates both RF1 and RF2 ports with 50 Ω resistive loads when those paths are OFF. Unlike reflective switches that present open or short circuits, this design maintains stable 50 Ω impedance at all ports regardless of switching state-preventing signal reflections that degrade VSWR, cause measurement errors, or damage sensitive components like LNAs or mixers downstream.
Can the HMC232LP4E handle +30 dBm RF input power?
The HMC232LP4E has an absolute maximum RF input power rating of +30 dBm (1 W) at +50°C ambient, per Absolute Maximum Ratings. However, linear operation is limited to +27 dBm (typical P1dB) - beyond which compression and distortion increase. For sustained reliability, continuous operation above +27 dBm should follow derating curves and thermal management guidance in the datasheet.
How does the HMC232LP4E differ from the HMC232LP4?
The HMC232LP4E is the RoHS-compliant version of the HMC232LP4. Key differences: HMC232LP4E uses 100% matte tin lead finish and has MSL1 rating with 260°C peak reflow temperature, while HMC232LP4 uses Sn/Pb solder and 235°C reflow limit. Both share identical electrical performance, pinout, package dimensions, and functional behavior - the HMC232LP4E replaces HMC232LP4 in new designs requiring lead-free compliance.
