A Robust GSM/EDGE Transmitter Using Polar Modulation Techniques

Christian Mayer, Burkhard Neurauter, Günter Märzinger, Christian Münker, Richard Hagelauer

Inhalt: 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 0.13µm CMOS technology, with a nominal margin of 7 dB to the critical 400 kHz specification and a transmit EVM of 2.5%.
