TriQuint's integrated digital variable gain attenuator for 3G/4G base stations

TriQuint's has innovated digital variable gain attenuators (DVGAs) that can reduce BOMs while providing automatic gain control for 3G / 4G base stations, repeaters and similar applications.

The TQM829007 (600 to 1000 MHz) and the TQM879008 (1.5 to 2.7 GHz) combine all required components in leadless 6x6mm, industry-standard packages. The modules include gain blocks, a highly-linear amplifier, matching components, bias chokes, blocking capacitors, and a digitally-controlled, 6-bit attenuator that varies gain through an SPI in 0.5dB steps from 0 to 31.5dB.

The DVGAs, along with GaN solutions for defense/aerospace, are exhibited at the WAMICON symposium in Cocoa Beach, FL (April 16-17).
