The initial application of the oscillator is within an automotive product. The use of Gunn technology provides performance advantages compared to competing technologies. The Gunn diode is a custom MBE grown GaAs hetrojunction device incorporated into a machined alloy body with an integral custom waveguide 26 flange. The oscillator is a radial mode 2nd harmonic bias tuned design. For microstrip applications a waveguide to 0.18mm microstrip step transition is available to interface the oscillator to microstrip circuits. A separate power supply driver PCB can be provided to interface to the Gunn module. This provides over voltage, spike and reverse polarity protection. The driver PCB also allows ease of frequency setting or the application of modulation. It should be noted that the Gunn diode is easily damaged by voltage transients or reverse bias. It is recommended that the...
