Abstract :
In this paper we present a dual-band transceiver IC for small, low cost handsets for GSM and DCS1800 applications. The IC fabricated in a 0.6-µm BiCMOS process includes a transmitter using the offset phase locked loop (OPLL) technique and a dual IF receiver. The evaluation results of the system containing the IC show the phase error of 3.0°rms (GSM) and 2.1°rms (DCS1800) for the transmitter, and the reference sensitivity of -106.2 dBm (GSM) and -105.9 dBm (DCS1800) for the receiver.
