UBEC Rolls out UW2453/UW2453L, the Smallest and Most Integrated 802.11b/g WLAN Transceiver Available in Market, Featuring High Performance, Low Power Consumption and an Integrated Power Amplifier

HSINCHU, Taiwan and MILPITAS, Calif., July 6 /PRNewswire/ -- UBEC (Uniband Electronic Corp.), a leading fabless semiconductor company specializing in WLAN RF transceivers, ZigBee(TM) compliant IC, WLAN/Bluetooth Power Amplifiers and Broadband Amplifiers for satellite receiver, announced today the mass production of UW2453/UW2453L, a highly integrated 802.11b/g WLAN transceiver with an integrated power amplifier and low power consumption. UW2453 has a nominal power output of +18 dBm while the UW2453L is a lower power, lower current consumption version of +14 dBm power output.

Built on the success of UW2451 and UW2452, UBEC's 11b/g and 11a/b/g transceivers respectively, the UW2453/UW2453L made a giant step forward by integrating the power amplifier and the PLL loop filter while reducing the die size and power consumption. UW2453/UW2453L feature an advanced transceiver architecture that integrates a PA, receive/transmit RF front end, VCO, Sigma-Delta PLL, loop filter, VGA, RSSI, RX/TX filter and advanced calibration circuits such as VCO calibration on a single chip. As such, the RF BOM is dramatically reduced by 50% from the previous design. UW2453/UW2453L further improve the RX DC cancellation gain settling time by incorporating UBEC's patented circuit design.

UW2453/UW2453L have a noise figure of 3 dB and consume 76 mA in the receive mode. At +18 dBm power output, UW2453 consumes 228 mA while the corresponding value is 160mA at +14 dBm power output for UW2453L. This makes UW2453/UW2453L highly desirable for WLAN products especially for portable devices such as VoIP in a mobile phone where the power consumption is a very critical consideration.

UW2453/UW2453L are housed in a 48-pin 7x7 mm2 QFN package. Similar to UW2451 and UW2452, UW2453/UW2453L require no external RF calibration to make an 802.11b/g WiFi and FCC compliant product.
