The series GDM mechanically-tuned Gunn oscillator is specifically designed to provide repeatable mechanical tuning characteristics by means of a micrometer drive. High power output is achieved with minimal output power variation over the entire tuning range. The oscillator provides broad tuning range with comparable output power from WR-28 to WR-10
