Sources Development for Millimeter-Wave Applications

摘要

The objective of this program is the design, fabrication, testing, and evaluation of 60 GHz and 94 GHz high power FM IMPATT DIODE transmitter oscillators and low noise local oscillators system tested for 100 megabits per second data rate communication at bit error rates (BER) of less than 10 to the -7th near the FM threshold. During the duration of this program, silicon double-drift IMPATT diodes on both copper and diamond heatsinks have been utilized and IMPATT transmitter oscillators of over 275 mW output power at 94 GHz and over 400 mW output power at 60 GHz have been developed. In addition, varactor tuned IMPATT diode local oscillators at 60 and 94 GHz frequencies have also been developed. System performance evaluation of these oscillators achieved BER of less than 10 to the -8th at signal-to-noise ratios meeting the program goal. (Author)
