Spectrum's Line of Dielectric Resonator Oscillators (DROs) and Coaxial Resonator Oscillators (CROs) are designed and built with both Small size and Low Phase Noise in mind. Packed full of standard features, our complete line of free running DRO designs operate from 500 MHz to 21.5 GHz, with "modified standard" units available in all frequencies from HF to Ku band.
At the core is our ceramic based resonators which have Very Low Loss and are Dependably Stable even during extreme temperature changes. To reduce Modulation Side-bands and Microphonics during high vibration & shock, our designs insure that the resonator is securely & firmly attached to the housing. All these features added together give you the Spectrum Advantage.
