SKY85321-21数据手册Skyworks中文资料规格书

描述 Description

The SKY85321-21 is a complete 802.11b/g/n/ac WLAN RF front-end module (FEM). The device provides all the functionality of a fully-matched power amplifier (PA), power detector, harmonic filter, low-noise amplifier (LNA), and single-pole, triple-throw(SP3T) switch.

The SKY85321-21 provides a complete 2.4 GHz WLAN RF solution from the transceiver output to the antenna, and from the antenna to the transceiver input.

The LNA increases the receive sensitivity of embedded solutions to improve range or to overcome cellular filter insertion loss (often included for mobile applications).

The SKY85321-21 also includes a transmitter power detector with 20 dB of dynamic range, and a digital enable control for transmitter power ramp on/off control.

The device is provided in a compact, 16-pin 2 x 2 mm Quad Flat No-Lead (QFN) package.
