UBEC's UW2451,
Highly Integrated WLAN 802.11g RF Transceiver, Offers
the Best Sensitivity and Dynamic Range in Class
HSINCHU, Taiwan and MILPITAS, Calif., Aug. 16, 2004 –
UBEC (Uniband Electronic Corp.), a leading wireless
communication IC design house specializing in RF
transceiver, satellite receiver and Zigbee™ ready
802.15.4 IC, announced today to mass product its low
power and highly integrated 802.11g transceiver chip.
High-performance reference boards of USB, MiniPCI,
CardBus and Compact Flash and reference boards to OEM/ODM
customers.
UW2451 Engineering samples have been tested in Q1 2004,
the field test results show that UW2451 significantly
improves RF performance over incumbent solutions on the
market such as 5 dB better in receiver sensitivity. This
is accomplished by the ultra low noise figure of just
2.5 dB of full receiver. Also, owing to its highly
linear receiver, UW2451 is able to operate to a maximum
input power of greater than 0 dBm in 54 Mbps. The
adjacent channel rejection is more than 15 dB better
than spec requirement. This allows UW2451 to work in
networks where interference causes issues, such as in
public or enterprise networks. UW2451’s patented
automatic DC cancellation and RSSI circuit enables super
fast AGC and antenna diversity. Its highly linear
transmitter beats the TX spectrum mask and EVM
requirement with a significant margin. UW2451 also
includes a Sigma-Delta synthesizer featuring low phase
noise, fast switching time and very flexible frequency
planning.
Housed in a 48-pin, 7*7 mm^2 QFN package, UW2451’s small
size and highly integration reduces customer's BOM
component count sharply. Its low power consumption is
also a strong candidate for applications such as
Cellular phone and WLAN VoIP and other wireless portable
devices.
UW2451 has been designed in major network devices
manufactures and notebook suppliers. The flexible radio
interface can work with different 11g Baseband/MAC ICs.
UBEC offers customers turnkey solutions for wireless LAN
and multimedia applications together with leading BB/MAC
partners.
UBEC also develops 802.11a/g multi-band transceiver;
samples of uw2452 are expected to be available in Q3
2004.
