65-nm CMOS DigRF EDGE Cellular Transceiver
The BCM2085 is a 65-nm CMOS single chip quad-band GSM/GPRS/EDGE RF transceiver for GSM850/EGSM900/DCS1800/PCS1900 voice and data applications. The monolithic die, designed on a 65-nm pure digital CMOS technology, integrates the transceiver core as well as the analog functionality to provide a digital interface compliant with the DigRF v1.12 standard. The BCM2085 offers a low power, highly integrated and low cost EDGE RF solution in a 4 mm x 4 mm package. It is the industry's smallest DigRF-compliant EDGE transceiver.
The BCM2085 delivers outstanding RF performance while achieving low power consumption through innovative architecture and circuit design. The RF transceiver draws upon Broadcom's extensive experience in pure digital CMOS radio design. Proprietary, autonomous, real-time calibrations within the radio ensure the BCM2085 delivers critical radio performance while using pure digital CMOS. Integration of the voltage controlled oscillators, synthesizers, and loop filters minimizes the board area and external component count.
