Abstract
A microstrip oscillator utilizing a Gunn diode as its active element for operation in the W-Band. A microstrip shunt resonator is dimensioned to resonate the Gunn diode at either its fundamental frequency or second harmonic frequency while a matching circuit, including a quarter wavelength transformer and a coupled microstrip transformer is employed to match the complex impedance of the Gunn diode device to the load. A radial hat on the Gunn diode effectively prevents radiation of electromagnetic energy from the system to thereby maximize the energy delivered to the load while, at the same time, functioning as a transformer element.
