The GSR2303 is a highly integrated front end module (FEM) designed for 2.4GHz 802.11b/g/n/ac systems. The device provides all the functionality of a fully matched power amplifier (PA), power detector, a 2.4G low-noise amplifier (LNA), and a single-pole, double-throw (SPDT) switches. The GSR2303 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 GSR2303 also includes a transmitter power detector with 20 dB dynamic range, and a digital enable control for transmitter power ramp on/off control. The device is provided in a compact, 16-pin 2.5 x 2.5 mm Quad Flat No-Lead (QFN) package.
