The letter describes the implementation of a phase-locking scheme described earlier to a 35 GHz Gunn solid-state source (SSS). The CLTF is developed, a loop filter is chosen and the response to a step disturbance is measured. This response is compare

Broadband varactor-tuned Gunn oscillators for Q band operation have been designed. One version using a reduced-height waveguide cavity has an electronic bandwidth of 1.18 GHz. Another using a coaxial cavity has a bandwidth of 3.05 GHz.

A scheme is described for using the injection-locking bandwidth of an electronically tuned microwave solid-state source to extend the locking to the limits of its electronic tuning range. The power supply current ‘hump’ phenomenon is used to slop

A system for measuring the weight of apples and oranges moving along a conveyor belt is described. The system relies on the effect of the moisture in the fruit on the resonant frequency and the Q-factor of a resonant waveguide cavity.

An alternative form of polar frequency discriminator is described. It reduces the complexity of previous circuits and makes microstrip integration much simpler by eliminating the need to cross over transmission lines. As a result phase errors are sig

It is shown how the effect of resistive losses in a varactor diode can drastically affect the tuning characteristics of millimetre-wave oscillators and can even cause the oscillator to tune in the reverse direction.
