A sum-frequency correlator for broadband PSK signals
Abstract
An experimental study is presented of a sum-frequency correlator circuit based on a nonlinear transmission line with varicaps, operating as a frequency doubler. The approach features spectral resolution of two PSK signals with precompression of their spectra. Time-lag values for the optimal mode of operation are obtained.
