BeRex Launches BVA1621 Wide-Band & High-Linearity Digital Variable Gain Amplifiers, For 5G/4G
23 Jun, 2025
GANGNAM-GU, South Korea – June 22, 2025 –PRLog— GANGNAM-GU, South Korea – BeRex today announced the release of a new product; the BVA1621 is a Digital Variable Gain Amplifier (DVGA) which is designed for glitch-safe attenuation state transitions, highly accurate 6-bit digitally-controlled attenuation over a 31.5 dB range, with 0.5 dB steps, while maintaining high linearity. The DVGA operates at its maximum frequencies of 4 GHz. The DVGA is powered by 5V and 3.3V supplies, which reduces overall power consumption, and is packaged in a space-saving 5mm x 5mm x 1.07mm, 32-Lead QFN.
Designed with outstanding RF characteristics, the DVGA is primarily intended for 5G/4G/3G wireless infrastructure equipment, satellite radio, and other high-end wireless applications. The BVA1621 offers flexibility to program gain control through Serial Mode, Latched Parallel Mode, and Direct Parallel Mode. Especially, Serial Mode with 3-bit Addressable function interfaces minimizes control lines that support very fast switching speeds.
