A New Method of QPSK Demodulation Based on Modified 26 GHz Six-Port Circuit
Keywords:
ADS software, direct conversion receiver, QPSK demodulator, Six-port circuitAbstract
In this paper, we propose to study a new demodulation technique of a QPSK signal exploited in a homodyne receiver by using a modified six-port circuit as demodulator. We will present two techniques of the same structure but we will retain only the best configuration. The new approach allows the integration of the receiver module in a high-performance millimeter wave technology, reducing the size and overall cost of the receivers. This approach is validated by using Agilent’s Advanced Design System (ADS) software for RF design and simulation.
