Microwave Dynamics offers a stable line of dielectric-resonator oscillators (DROs) for applications from 3 to 50 GHz. Ideal for satellite communications, point-to-point microwave radios, test equipment, and a wide range of military systems, these sources feature a 100-MHz mechanical tuning range and electrical tuning as an option. They provide +13 dBm output power in standard units, with as much as +25 dBm output power as an option. Output power is flat within 1 dB. Spurious levels are -85 dBc while harmonics are -25 dBc. Phase noise is better than -109 dBc/Hz offset 10 kHz from a 4-GHz carrier and -90 dBc/Hz offset 10 kHz from a 22-GHz carrier. The compact DROs measure just 2.25 x 0.93 x 0.67 inches with female SMA connectors.
