BeRex Launches the Industry's First Wideband Digital Variable Gain Amplifiers Needing Only a Single 3V Power
Supply
State-of-the-art Digital Variable Gain Amplifiers provide very low power consumption.
San Jose, CA, February 2, 2015. BeRex today announced the BVA303 and BVA305, 6-bit DVGA (Digital
Variable Gain Amplifiers) offering high linearity, low noise and require only a single 3V power supply, thereby
reducing the power consumption. Both DVGAs are capable of working at up to 4GHz without external matching components
and are provided in a space saving 4x4mm, 24- pin QFN package.
Designed primarily for 3G/4G wireless infrastructure equipment, satellite radio and other high end wireless
applications, the BVA303 and BVA305 provide outstanding RF characteristics and the flexibility of digital parallel
and serial programming of the gain control that provides very fast switching speeds.
