Planar gunn diode characterisation and resonator elements to realise oscillator circuits

The paper describes the planar Gunn diode, which is a device well suited to provide milli-metric and tera-hertz sources using microwave monolithic integrated circuit technologies. Different planar Gunn electrode geometries are described along with DC, RF and thermal characterisation. To realize the planar high frequency sources there is requirement for high frequency planar resonators, the paper will describe both the radial and new diamond shaped geometries.
