BeRex Launches BVA1761, BVA1762, BVA2761 and BVA2762 Ultra-Flat Gain Wide-Band & High-Linearity DVGA

State-of-the-art Digital Variable Gain Amplifiers(DVGAs) with very low power consumption for 5G/4G/3G Wireless Infrastructure applications.
GANGNAM-GU, South Korea - Oct. 20, 2022 - PRLog -- GANGNAM-GU, South Korea - BeRex today announced the release of four (4) new products; the BVA1761, BVA1762, BVA2761 and BVA2762 are Digital Variable Gain Amplifiers (DVGAs) which are designed for glitch-safe attenuation state transitions, highly-accurate 7-bit digitally-controlled attenuation over a 31.75dB range, with 0.25dB steps, while maintaining high linearity.  The DVGAs operate at their maximum frequencies of either 6GHz, or 8GHz.  The DVGAs are powered by 5V, 4V and 3.3V supplies, which reduces their overall power consumption, and they are packaged in the space saving 4mmx4mmx0.9mm, 24-Lead QFN and 5mmx5mmx0.9mm, 32-Lead QFN.

Designed with outstanding RF characteristics, the DVGAs are primarily intended for 5G/4G/3G wireless infrastructure equipment, satellite radio, and other high-end wireless applications.  The BVA1761, BVA1762, BVA2761 and BVA2762 offer the flexibility to program their gain-control through serial mode only and 2-3bit Addressable function interfaces to minimize control lines that support very fast switching speeds.
