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.
