SKY85325-11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 SKY85325-11 is a complete 802.11 256 QAM WLAN RFfront-end module (FEM). The device provides all the functionalityof a fully matched power amplifier (PA), power detector,low-noise amplifier (LNA), and single-pole, double-throw (SPDT)switch.

The SKY85325-11 provides a complete 2.4 GHz WLAN RF solutionfrom the output of the transceiver to the antenna, and from theantenna to the input of the transceiver. The LNA increases thereceive sensitivity of embedded solutions to improve range.The SKY85325-11 also includes a transmitter power detector with20 dB of dynamic range, and a digital enable control fortransmitter power ramp on/off control.

The device is provided in an ultra-compact, 16-pin, 2.5 x 2.5 mmQuad Flat No-Lead (QFN) package.
