概述

Description

HMC909LP4ETR is a microwave/mmWave IC from Hittite Microwave (now Analog Devices) in a compact 4-lead leadless plastic package. The “LP4” denotes a 4-pin leadless package and “ETR” indicates Tape & Reel packaging. It’s a broadband RF/microwave MMIC device intended for front-end applications such as receivers or transmitters, often used in mixing, amplification, or related RF functions depending on the exact model family.
Key points:
- Manufacturer: Hittite Microwave / Analog Devices
- Package: 4-pin leadless plastic (LP4); ETR = tape-and-reel
- Application: RF/microwave front-ends (broadband, high-frequency)
- Needs: external biasing and RF matching networks; consult datasheet for pinout and operating conditions
- For precise specs (frequency range, gain/ NF/IP3, LO/RF/IF ports, bias voltages), refer to the official HMC909LP4ETR datasheet
If you want, I can summarize the exact specs from the datasheet.

Package

Plastic 4-lead surface-mount package (LP4). RoHS-compliant, Tape & Reel (ETR).

Pinout

Pin count: 4 pins (LP4 leadless package). Function: RF limiter (GaAs MMIC limiter) used as front-end protection/proper attenuation in microwave receiver chains.

Manufacturer

Analog Devices, Inc. (the HMC line originated from Hittite Microwave, which ADI acquired). Analog Devices is a global semiconductor company that designs and manufactures analog, mixed-signal, and RF/microwave integrated circuits for communications, industrial, automotive, and healthcare applications.

Application

Applications: RF/microwave front-end modules for wireless, radar, and satellite communications. Typical uses include receivers/transceivers for cellular backhaul (2G/3G/4G/5G), point-to-point microwave links, automotive/aerospace radar, SATCOM terminals, and instrumentation/test equipment. The HMC909LP4ETR can serve as a mixer, down/up converter, LNA, or gain block in a compact MMIC form to enable wideband conversion and amplification.
