Dielectric Resonator Oscillators & Coaxial Resonator Oscillators

API'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.

Frequency Generation Features
Superior Engineering
Ultra Low Phase Noise

Our ceramic based resonators are very low loss and 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.

Screened high performance voltage tuned varactor diodes for tuning repeatability.

Features custom thin film microstrip boards for improved noise performance.

Our .500” square surface mount DRO designs offer low cost and a smaller footprint.

We design our own filters in-house allowing fine tuning for optimum performance.

Better receiver sensitivity and
enhanced system noise floor.

Metalized PC backplanes are used for improved grounding and superior stability.
