This 0.5 μm SiGe BiCMOS polar modulator IC adds EDGE transmit capability to a GSM transceiver IC without any RF filters. The modulator achieves phase noise of -152 dBc/Hz and -164 dBc/Hz at 10 MHz and 20 MHz, respectively, with a measured EVM of 3%. The IC consumes 55 mA and 75 mA at 2.7 V for GSM and EDGE, respectively.
