Abstract :
The design and performance results of a Ku-band voltage controlled oscillator subsystem using a broadband GaAs MMIC (monolithic microwave integrated circuit) push-pull amplifier as a frequency doubler are described. The subsystem utilizes both GaAs MMIC and Si bipolar technologies to achieve the desired performance objectives. The oscillator subsystem is tunable over the 14-18-GHz frequency range with a minimum output power of 18 dBm and a phase noise of -88 dBc/Hz at 100-kHz offset from the carrier over a 0 to +65 degrees C temperature range.<>
