Computer aided design of a microwave MESFET DRO

Describes the extension of an oscillator synthesis procedure, to incorporate a coupled dielectric resonator (DR) and hence enable the synthesis of a MESFET DRO (dielectric resonator stabilised oscillator). The synthesis strategy employed for MESFET oscillator design is described. This technique uses the large-signal device circuit model to predict the external terminations necessary for maximum output power at a specified frequency. The next section describes the DR mounting configuration, the resulting equivalent circuit and the method by which it is incorporated into the synthesis procedure. Finally the method is used to design a 13.8 GHz DRO, using a NE71000 chip MESFET
