  • Abstract
    A K-band high-power and highly stable power source has been developed using a cavity-stabilized IMPATT-diode oscillator followed by a one-stage high-power reflection-type IMPATT-diode amplifier. The power source shows an output power of 0.7 W, a temperature coefficient of 6x10-7 / °C, and an FM noise level of 92-Hz rms/1-kHz BW at 100 kHz from the carrier. To achieve a highly stable oscillation, free from mode jumping, a new hybrid-coupled cavity circuit with a passivating absorber is applied to stabilize the oscillation. The high-power amplifier is designed using a measured large signal device admittance and a power-adding concept.
