Description

While bias-tuned Gunn oscillators are suitable in many applications requiring frequency control, in those cases where the modulating signal frequency is very high or the tuning range is large, an alternative method of electronic tuning is required. FTL's range of varactor-tuned Gunn oscillators has been developed to meet these requirements.

The modulating signal frequency may be very high (into the microwave region if necessary) and the varactor tuning range has been achieved with high output power and minimal power variation. Wideband units and units fitted with mechanical tuning are also available. Highly linear VCO tuning characteristics are available for use with digital radio modulation schemes.

Two basic types of varactor tuned Gunn are available; series tuned and parallel tuned. The series tuned versions offer the maximum tuning bandwidth at the expense of output power. Parallel tuned designs deliver higher power levels but have restricted bandwidth.

Notes

     
  1. For requirements beyond 100 GHz we suggest higher power injection locked designs. Contact FTL for details.
