BGA735X: 50 MHz to 250 MHz high linearity Si variable gain amplifier; 24 dB gain range

Overview

The BGA7350 MMIC is a dual independently digitally controlled IF Variable Gain Amplifier (VGA) operating from 50 MHz to 250 MHz. Each IF VGA amplifies with a gain range of 24 dB and at its maximum gain setting delivers 17 dBm output power at 1 dB gain compression and a superior linear performance. The BGA7350 Dual IF VGA is optimized for a differential gain error of less than ±0.1 dB for accurate gain control and has a total integrated gain error of less than ±0.4 dB. The gain controls of each amplifier are separate digital gain-control word, which is provided externally through two sets of 5 bits. The BGA7350 is housed in a 32 pins 5 mm x 5 mm leadless HVQFN32 package.
