50 MHz to 500 MHz High-Linearity Si Variable-Gain Amplifier (28 dB Gain Range)
BGA7351 Receive alerts
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 x 5 mm leadless HVQFN32 package.
