In addition, frequency multiplication of mm sources such as Gunn oscillators
instead of microwave sources permits large dynamic ranges and good frequency coverage to be obtained.
For frequencies above 200 GHz, mm-wave Gunn oscillators
, phase-locked to the analyzer reference, and followed by Schottky diode harmonic generators and/or harmonic mixers, can also be used as relay sources.
The bias-tuned Gunn oscillator
configuration exhibits a clean, stable bias-tuned signal from 9.2 to 9.47 GHz with a power output of 14.2 |+ or -~ 1.5 dBm.
The local oscillator consists of a Gunn oscillator
that is phase locked to a type TCI M5020 crystal controlled microwave source via a harmonic mixer.
A lumped-element Gunn oscillator
at 45.69 GHz provided a LO drive to the mixer.
Advances have been made in microwave and mm-wave Gunn oscillator
and VCO technology.
Without the mode suppressor, the Gunn oscillator
and circulator design successfully could not be realized.
This Coho is a low noise, low power (+7 dBm) Gunn oscillator
tuned to the injected frequency.
A fundamental frequency Gunn oscillator
was used as the RF source in the experiments described in this article.
For applications such as band compression in surveillance receivers and frequency processing in mm-wave radars, engineers at AEG have developed a harmonically primed GaAs Gunn oscillator
acting as a wide bandwidth 94/47 GHz frequency halver.
The key to making these measurements stems from the generation of extremely stable reference signals which are synthesized by the combination of an ultra-stable sapphire resonator (oscillator), a set of low-noise regenerative dividers, and a set of cavity-stabilized Gunn oscillators
. To date there have been no high-stability reference sources for measurements across this frequency region.
