These 6-bit digital VGAs offer high linearity (35 dBm @ 2.2-2.8 GHz) and high output power

(23 dBm @ 2.2-2.8 GHz) across a large bandwidth without external matching. Smart routing with no

connection crosses simplifies design and decreases footprint by 25%. The unique power-save mode

can effectively reduce the current consumption in TDD systems up to 45%. The BGA7210 adds flexible

current distribution across its two amplifiers, depending on the attenuation state, to save current.

Key features
