SKY85712-21中文资料5 GHz WLAN Front-end Module数据手册Skyworks规格书

描述 Description

The SKY85712-21 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 Low-Noise Amplifier (LNA)with bypass, and a 5 GHz Power Amplifier (PA) intended formobile/portable 802.11ac applications and systems.

The LNA and PA disable functions ensure low leakage current inoff mode. An integrated power detector is included to provideclosed-loop power control within the system.

The device is provided in a compact, 16-pin 3 x 3 mm Quad FlatNo-Lead (QFN) package.
