Monolithic microwave FET oscillator temperature-stabilised with a Schottky diode as a sensor

A monolithic microwave FET oscillator built in GaAs is frequency-stabilised with temperature using a Schottky diode as a temperature sensor. The monolithic integrated circuit includes both the oscillator (f=7.44 GHz) and its temperature sensor. The actual performance gives a stabilisation of the frequency to better than 1 MHz in the temperature range from −40 to +80°C.
