![Berex Releases Four New Digital Variable Gain Amplifiers that Operate up to 8 GHz](https://cdn.everythingrf.com/website/global/gray-svg-image.svg)
BeRex, a company that designs, develops and supports innovative RF and microwave semiconductors in bare die and surface mount packages for current and next-generation wireless communication equipment, has released four new amplifier products: BVA1761, BVA1762, BVA2761 and BVA2762.
These Digital Variable Gain Amplifiers (DVGAs) are designed for glitch-safe attenuation state transitions, highly accurate 7-bit digitally-controlled attenuation over a 31.75 dB range, with 0.25 dB steps, while maintaining high linearity. The DVGAs operate at maximum frequencies of either 6 GHz, or 8 GHz. The DVGAs are powered by 5 V, 4 V and 3.3 V supplies, which reduce their overall power consumption, and are packaged in the space-saving 4 mm x 4 mm x 0.9 mm, 24-Lead QFN and 5 mm x 5 mm x 0.9 mm, 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 2-3 bit addressable function interfaces to minimize control lines that support very fast switching speeds.
