The F6921 is an ultra-low power consumption, dual-channel, low noise amplifier (LNA) RFIC designed for application in Ku- Band SATCOM planar phased array antennas. The exceptional combination of low power consumption, low noise, high gain, and compact size, maximizes the antenna array G/T while minimizing overall system power dissipation. An external bias current provides gain control, standby mode and temperature compensation.

The F6921 includes two independent gain/phase matched LNA channels in a compact 23-pin, 0.5mm pitch BGA package. All inputs and outputs are single-ended and 50Ω matched for ease of integration on to phased array antenna panels.
