Abstract
A key property of polar modulator systems is the matching between amplitude and phase path. This paper shows how mismatches between these paths degrade performance and introduce difficulties in designing GSM/EDGE systems. A transmitter overcoming these problems is presented. The chip has been implemented in a 0.13mum CMOS technology, with a nominal margin of 7 dB to the critical 400 kHz specification and a transmit EVM of 2.5%
