Abstract
A microwave source has an amplifying transistor capable of operating at microwave frequencies and a frequency selection circuit. The circuit has a whispering mode dielectric resonator and a feedback loop having a first microstrip line connected by an impedance adaptation circuit to a gate of said transistor and a second microstrip line connected by an impedance adaptation circuit to a drain of said transistor. The dielectric resonator is located between the first line and the second line for magnetic field coupling therewith.
