Abstract :
A lightweight 14 GHz, 120 Mbit/s differential QPSK demodulator for satellite application is described. The demodulator comprises a low-loss, temperature-stable waveguide delay filter and high-sensitive phase detectors. With this combination low-level operation and a high dynamic range are obtained.
