Planar GaAs Mott mixer diodes have been made for use in novel E-plane balanced mixers at 35 and 85 GHz. Single sideband noise figures of 6 dB at 35 GHz and 7.5 dB at 85 GHz (including 1 dB I.F. contribution) have been achieved. Both devices and circu

E-plane circuit techniques have been shown to be suitable for realising millimetric components for frequencies from 27 to 140 GHz. This paper describes the use of this technology for a portable radio link equipment for use in the 27.5 to 29.5 GHz ban

This paper describes the design and performance of balanced mixers for use in the frequency ranges 27 to 40 GHz and 60 to 90 GHz. The transmission medium used is integrated finline which is potentially cheap to produce and has lower loss than microst

An injection-locking technique whereby a varactor-tuned Gunn oscillator is connected directly to a high-power impatt oscillator is described. The technique does not require a circulator and results in a compact, high-power, electronically tunable sou

Research into a novel class of distributed amplifiers which have a high isolation bandstop response in the reverse gain direction is described. These devices may be used as duplexer/circulator or bidirectional amplifier elements which, for many appli

Measurements performed on a 2nd-harmonic transferred-electron oscillator and a scale model are reported. A method is described for determining the resonant frequency of the oscillator once the diode parasitic reactances are defined.

The paper describes the design of a new class of microstrip bandstop filter. This filter is a very compact structure, it radiates power significantly less than conventional shunt-stub and coupled-line filters and is also less susceptible to the influ

A novel design of varactor-tuned millimetre-wave second-harmonic Gunn oscillator is reported in which a varactor is mounted in a secondary cavity resonant at the fundamental frequency of the Gunn diode. This has the advantage that the varactor does n
