SKY85300-21

2.4 GHz, 256 QAM Front-End Module for WLAN and Bluetooth® Applications


Please note: SKY85300-21 is being discontinued and is not recommended for new designs. The suggested replacement is SKY85310-21

The SKY85300-21 is a complete 802.11b/g/n 256 QAM WLAN RF front-end module (FEM) with a port suitable for Bluetooth® signals. The device provides all functionality of a fully matched power amplifier (PA), power detector, harmonic filter, low-noise amplifier (LNA), and single-pole, triple-throw (SP3T) switch.

The SKY85300-21 provides a complete 2.4 GHz WLAN RF solution from the output of the transceiver to the antenna, and from the antenna to the input of the transceiver. The LNA increases the receive sensitivity of embedded solutions to improve range or to overcome the insertion loss of cellular filters (often included for mobile applications).

The SKY85300-21 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 an ultracompact, 16-pin 3 x 3 mm Quad Flat No-Lead (QFN) package.
