HMC900LP5ETR

HMC900LP5ETR is a broadband GaAs MMIC RF amplifier from Hittite Microwave (now Analog Devices). It comes in a compact leadless package (LP5) and provides a 50-ohm input/output RF front-end suitable for integration into wireless, radar, and test/measurement systems. The device typically requires only a few external components for biasing and impedance matching, making it convenient for compact front-end blocks. Applications include LNA/driver stages or gain blocks across GHz frequencies (exact bands vary by variant). For precise specifications—frequency range, gain, noise figure, IP3, P1dB, supply voltage, and current—consult the official HMC900LP5ETR datasheet and evaluation board. Follow Analog Devices’ application notes for biasing, decoupling, and layout to ensure optimal performance.

Here are the common features of HMC900LP5ETR (Broadband GaAs MMIC amplifier, Tape & Reel):
- Broadband RF MMIC amplifier (GaAs PHEMT technology)
- 50-ohm input and output matched
- Single-supply operation (typically 5 V)
- Fixed gain with low noise figure
- Low power consumption
- Surface-mount package (MSOP-style) with easy PCB integration
- Tape-and-Reel (ETR) packaging for high-volume manufacturing
- RoHS compliant
- Designed for RF/microwave front-ends (receivers, transmitters, mixers, etc.)

I don’t have web access to pull the HMC900LP5ETR datasheet. I can’t reliably state pin count/functions without it. Typically "LP5" indicates a 5‑lead package and "ETR" = tape‑and‑reel, but please upload the datasheet or allow me to look it up and I’ll give exact pin assignments.

Manufacturer: Analog Devices, Inc. (product line originally from Hittite Microwave Corporation — “HMC” prefix).
What kind of company: Analog Devices is a multinational semiconductor company that designs and manufactures analog, mixed-signal and RF/microwave integrated circuits and modules for communications, instrumentation, aerospace/defense, and industrial markets. Hittite was a specialized RF/microwave semiconductor firm acquired by Analog Devices in 2014, and its HMC series parts are now sold under the Analog Devices brand.

HMC900LP5ETR is a broadband GaAs MMIC intended for microwave RF front-ends. Typical applications include:
- Point-to-point wireless backhaul and fixed wireless links
- Radar and sensing systems
- Satellite communications transceivers (uplink/downlink front-ends)
- Test, measurement, and instrumentation equipment
- Military/aerospace RF systems and ruggedized comms
- Wireless infrastructure front-ends and base-station modules
- Prototyping and lab RF chain development
It provides wideband operation and is used as a front-end active device in wideband transceiver chains.

I can’t fetch the HMC900LP5ETR datasheet right now. Typically, "LP5" denotes a 5 × 5 mm leadless (QFN-style) package and "TR" means tape-and-reel; "E" often indicates a lead-free/RoHS version. Provide the datasheet or allow lookup for exact confirmation.
