DESCRIPTION:
SOM series mechanically tuned Gunn oscillators utilize high performance GaAs Gunn diodes and various cavity designs to deliver moderate output
power with low AM/FM noise and harmonic emissions. Compared to their counterparts, such as multiplier based sources, Gunn oscillators offer abroader mechanical tuning capability and lower cost solution. The standard offering covers the frequency range of 8.2 to 140 GHz. While standard
models are equipped with a micrometer for bench test purpose, models with a self-locking set screw are also available for system integration. The
performance of the oscillator can be further enhanced by adding an optional isolator, Gunn oscillator modulator/regulator and temperature heater.
