FM7705 IC

The device is sold in a RoHS compliant
miniature 5 x 5 x 0.8 mm 20-pin QFN package
to make automated assembly simple.

The FM7705 is a fully integrated RF front-end
module designed for dual-band tri-mode
802.11 a/b/g WLAN applications. The device
includes a T/R switch, a broad band LNA, a
receive Band Pass diplexer, a transmit High
Pass/Low Pass diplexer, 2.4GHz and 5 GHz
high power linearized power amplifiers, and a
built-in transmit power detector. Biasing and
matching circuitry are integrated to minimize
the external components required.

Applications
1. EEE 802.11a / b / g / n 1T1R
2. IEEE 802.11a / b / g WLAN
