Abstract :
Results are presented of the design and performance of a microstrip transmitter/receiver circuit using thick-film yttrium barium copper oxide on a yttria-stabilised zirconia substrate. The resonant circuit is in the form of a ring resonator and the active component is a transferred electron device integrated within the circumference of the ring. In receive mode, the circuit operates as a self-oscillating mixer. Operating frequencies lie in the range 8 to 16 GHz and measurements include: Q-factor by injection phase locking; oscillator output power and conversion loss.<>
