Abstract :
A Ku-band nondegenerate parametric amplifier using a single-packaged GaAs varactor diode is described. A very simple structure of the single-tuned amplifier with a new type of idler choke is employed to obtain a large voltage-gain bandwidth product and a low noise temperature. The double-tuned operation exhibits a nearly flat bandwidth of 550 MHz at a 20-dB gain and a noise temperature of 280°K at room-temperature ambience.
