“…The design of the developed correlator, named the A correlator, based on rat-race hybrids [33], is presented in Figure 3. The first functional block of the correlator is the proportional (frequency-proportional) phase shift, forming network build of power divider PD1 and transmission lines DL and TL.…”

“…Modern discriminators should work as accurately as possible, be small in size, and not require complex technologies for their manufacturing. The unique pattern of integrated quadrature microwave frequency discriminator (i.e., proportional phase shift forming network and six-port on a single PCB) was developed by authors, and shortly presented in conference paper [33]. This QMFD was designed to run over one of the Wi-Fi frequency bands.…”

Instantaneous frequency measurement devices are useful for conducting extremely fast measurements of the current frequency value of microwave signals, even if their duration is extremely short. This paper presents the principle of determination of temporary values of the microwave signal phase and frequency using interferometer techniques, based on passive microwave components. Additionally, the structures and results of measurements of two novel versions of integrated microwave correlators for microwave frequency discriminators, made on a single printed circuit board, are shown. Three Wilkinson-type, single-stage power dividers, and two rat-race hybrids create the developed correlators. The developed devices were designed to work over a wide frequency range, i.e., of 1.6–3.1 GHz, and can be used to monitor Wi-Fi devices as well as pulse and CW radar systems operating in the S band. They can also be applied in passive radars and active Doppler radars. The view of the printed circuits boards and results of measurements are presented. Recommendations for improving the accuracy of measurement are proposed.
