Berkäna Wireless introduces a family of single-chip CMOS transceivers. The BKW9000 transceivers feature receiver performance across all four bands with a sensitivity as low as 110 dBm while consuming approximately 90 mA current. The 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 transceivers require 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. The transceivers occupy less than 1.1 cm2 of printed circuit board (PCB) area for the transceiver function. The transceiver family consists of the BKW9088 and BKW9089 transceivers. The BKW9088 uses an external voltage-controlled temperature-compensated crystal oscillator (VC-TCXO) module. The BKW9089 offers an integrated temperature-compensated digitally controlled crystal oscillator (TC-DCXO) function, requiring only an external low-cost crystal.
