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 FCCSP (BGA) package with 50Ω matched single-ended RF inputs and outputs for ease of integration onto phased array antenna panels.
