SKY85331-11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 SKY85331-11 is a highly integrated, 2.4 GHz front-endmodule (FEM) incorporating a 2.4 GHz single-pole, double-throw(SPDT) transmit/receive (T/R) switch, a 2.4 GHz low-noiseamplifier (LNA) with bypass, and a 2.4 GHz power amplifier (PA)intended for high-power 802.11ax applications and systems.

The LNA and PA disable functions ensure low leakage current inthe off mode. An integrated logarithmic power detector isincluded to provide closed-loop power control over 20 dB ofdynamic range.

The device is provided in a compact 24-pin 3 x 5 mm conformallyshielded Land Grid Array (LGA) package, which may reduce thefront-end board space by more than 50 percent.
