CAMPBELL, Calif. -- Berkäna Wireless Inc., a provider of highly integrated CMOS radio frequency (RF) solutions for cellular and other multi-mode wireless connectivity, announced the introduction of a new family of single-chip CMOS transceivers offering the industry's best combination of performance, power and integration of any quad-band GSM/GPRS RFIC (Radio Frequency Integrated Circuit). The BKW9000 Transceivers feature a superior receiver performance across all four bands with a sensitivity as low as -110 dBm while consuming approximately 90 mA current. This combination of high performance and low power consumption ensures fewer dropped calls, better call quality and helps extend the battery life of cellular handsets and mobile terminals.

The Berkäna BKW9000 Transceivers support GSM-850, EGSM-900, DCS-1800 and PCS-1900 bands through the integration of four low-noise amplifiers (LNAs), complete receiver and transmitter chains, synthesizers and filters. The BKW9000 Transceivers help reduce Bill of Materials (BOM) cost, requiring only five additional components to implement a quad-band GSM/GPRS Class 12 transceiver circuit. No external LC filters, transmit filters, transmit baluns, IF SAW filters or VCO modules are required. In addition, the BKW9000 Transceivers enable smaller form-factor handsets by occupying less than 1.1 cm² of printed circuit board (PCB) area for the transceiver function, which is more than 50 percent smaller than the 2.4 cm2 of PCB space typically required by alternative solutions.

"The Berkäna BKW9000 Transceivers offer the highest level of integration and feature a receiver performance and power consumption that is about 20 percent better than any other single-chip quad-band GSM/GPRS transceiver," said Dr. Beomsup Kim, co-founder and CTO of Berkäna Wireless, a recognized communications expert and an IEEE Fellow.
