TQM879008

Product Overview

TQM879008 is a Qorvo (formerly TriQuint Semiconductor) digital variable gain amplifier (DVGA) designed for wireless infrastructure and RF communication applications. Operating from 1.4GHz to 2.7GHz, this module integrates two gain stages, a digital step attenuator (DSA) and a high-linearity 0.5W amplifier in a compact 28-pin 6mm × 6mm leadless SMT package. With up to 41.1dB gain, 31.5dB digital gain adjustment range and excellent linearity performance, it is suitable for 3G/4G base stations, repeaters, LTE infrastructure and RF signal processing systems.
