BGA7351

+94)1 BGA7351 50 MHz to 500 MHz high linearity Si variable gain amplifier; 28 dB gain range Rev. 3 — 11 June 2014 Product data sheet 1. Product profile 1.1 General description The BGA7351 MMIC is a dual independently digitally controlled IF Variable Gain Amplifier (VGA) operating from 50 MHz to 500 MHz. Each IF VGA amplifies with a gain range of 28 dB and at its maximum gain setting delivers 16.5 dBm output power at 1 dB gain compression and a superior linear performance. The BGA7351 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 0.3 dB. Moreover it meets the demanding phase error requirements for GSM. BGA7351 has less than 3.0 phase error over the full gain range of 28 dB. The gain controls of each amplifier are separate digital gain-control word, which is provided externally through two sets of 5 bits. The BGA7351 is housed in a 32 pins 5 mm  5 mm leadless HVQFN32 package. 1.2 Features and benefits  Dual independent digitally controlled 28 dB gain range VGAs, with 5-bit control interface  50 MHz to 500 MHz frequency operating range  Gain step size: 1 dB  0.1 dB  22 dB power gain  Fast gain stage switching capability  16.5 dBm output power at 1 dB gain compression  46 dBm third order intercept point  Constant third order intercept point over output power  85 dBc second harmonic level  Excellent noise figure of 6 dB  5 V single supply operation with...
