The F6922 is an ultra-low power consumption, dual-

channel, low noise amplifier (LNA) RFIC designed

for application in Ka-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 F6922 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.
