The SKY85347-11 from Skyworks Solutions is a 2.4 GHz WLAN Front-End Module. It consists of a 2.4 GHz fully matched power amplifier (PA), positive slope power detector, low-noise amplifier (LNA) with integrated bypass mode, and single-pole double-throw (SPDT) switch. This module also includes a transmitter power detector with 26 dB of dynamic range and a digital enable control for transmitter power ramp ON/OFF control. It 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.
The SKY85347-11 supports modulation up to 1024 QAM and provides a gain of 32.5 dB (transmit) and 16.5 dB (receive). It is available in a small 16-pin laminate package that measures 3 x 3 mm and is ideal for 802.11ax set-top boxes, networking, personal computer systems, PC cards, PCMCIA cards, mini-cards, and half mini-cards and WLAN-enabled wireless video systems applications.
