An Analog Synchronous QPSK Demodulator for Ultra-High Rate Wireless Communications

A. Cagri Ulusoy, Gang Liu, Andreas Trasser, and Hermann Schumacher

The paper was presented at the German Microwave Conference (GeMiC), Darmstadt, 2011 ( www.gemic2011.tu-darmstadt.de ).

Abstract: In this paper, the authors present a monolithic integrated QPSK demodulator, which performs carrier phase and frequency synchronization in the analog domain. Analog synchronization eliminates the need for high speed and high resolution analog to digital converters (ADC), which makes the presented demodulator especially promising for communication links exceeding gigabits-per-second data rates. Within this paper, analog carrier recovery, and successful synchronous demodulation is experimentally demonstrated for data rates up to 3.5 Gbit/s. The presented MMIC is realized in Telefunken SiGe2RF HBT technology (fT and fmax ≈ 80 GHz), and operates at an intermediate frequency of 5 GHz. The IC is supplied from a single 2.5V DC source and consumes 110mA current.
