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.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
