Introduction

The SKY85728- 11 is a highly integrated, 5 GHz front- end module (FEM) incorporating a 5 GHz single- pole, double- throw (SPDT) transmit/receive (T/R) switch, a 5 GHz high- gain low- noise amplifier (LNA) with bypass, and a 5 GHz power amplifier (PA) intended for high- power 802.11ac applications and systems. The LNA and PA disable functions ensure low leakage current in the off mode. An integrated power detector is included to provide closed- loop power control within the system. The device is provided in a compact, 24- pin 3 × 5 mm Quad Flat No- Lead (QFN) package, which may reduce the front- end board space by more than 50 percent.
