SKY85309-11数据手册RF/IF射频/中频RFID的射频前端（LNA+PA）规格书PDF

描述 Description

The SKY85309-11 is a highly integrated, 2.4 GHz front-end module(FEM) incorporating a 2.4 GHz single-pole, double-throw (SPDT)transmit/receive (T/R) switch, a 2.4 GHz low-noise amplifier (LNA)with bypass, and a 2.4 GHz power amplifier (PA) intended forhigh-power 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, 24-pin 3 x 5 mm Quad FlatNo-Lead (QFN) package.
