Abstract
Oscillators that operate at 720 and 940 MHz and characterized over a temperature range of 25 °C to 200 °C and 250 °C, respectively, are presented. The oscillators are designed on alumina substrates with typical integrated circuit fabrication techniques. Cree SiC MESFETs, thin film metal-insulator-metal capacitors and spiral inductors, and Johanson miniature chip antennas make-up the circuits. The output power and phase noise are presented as a function of temperature and frequency.
