Description

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 externally supplied reference

bias current is used to trade LNA power consumption against P1dB

and gain, completely shut off (idle) the amplifier during operation or

for gain compensation versus temperature.

The LNA is supplied in a compact 23-pin, 0.5mm pitch BGA

package with 50Ω matched single-ended RF inputs and outputs for

ease of integration onto phased array antenna panels.
