The UW2453 is a fully integrated single-chip transceiver (including PA) specifically designed for IEEE802.11b/g wireless local area networks (WLANs) applications. It features data rate 6, 9, 12, 18, 24, 36, 48 and 54 Mbits/s in OFDM mode, 5.5 and 11 Mbits/s in CCK mode, 1 and 2 Mbits/s in DSSS mode. The UW2453 integrates a receiver and transmitter, VCO and PLL as well as a power amplifier into a single IC. Only one or two switches, one RF bandpass filter, one low pass filter, and several passive components are required to build a spec compliant 11b/g radio. The patented DC cancellation technique allows the receiver set its gain at super fast speed for the gain settling in the OFDM mode. The patent pending power amplifier design assures a very good TX linearity at a minimum current consumption. The UW2453 is fabricated with advanced SiGe BiCMOS process and is housed in a 48-pin QFN 7x7 mm² package.

The low power consumption of the UW2453 makes it an ideal candidate for WLAN applications in desktop/laptop PC, handheld devices, and mobile handsets.
