Y-Band (170-260 GHz) Tunable CW IMPATT Diode Oscillators

This paper describes circuit, packaging, and device techniques used in the development of tunable CW IMPATT diode oscillators in the 170-260 GHz range. A quartz standoff package with optimum values for parasitics has been developed. A tuning range of nearly 30 GHz has been achieved with an IMPATT diode in such a package.
