Description 
The GC1125 is an integrated Front-End Module (FEM) for an IEEE 802.11ac system. It includes a highly linear 5GHz Power Amplifier (PA) with power detector, Low Noise Amplifier (LNA) with bypass capability, and SPDT antenna switch. The compact form factor and integrated matching minimizes layout area in the application.

Performance is mainly focused on optimizing the power amplifier and Low Noise Amplifier under a 5V supply voltage. The PA and LNA disable functions ensure very low leakage current in off mode. An integrated power detector is included to provide closed-loop power control within the system.

The GC1125 is available in a 16-pin low profile 2.5x2.5x0.65mm QFN Package
