DRO-1500 series is MD’s new Mini-DRO series, with a super compact package of 1.2″ x 1.2″ x .660″. DRO-1500 Series Dielectric Resonator Oscillator (DRO) utilizes state-of-the-art MIC to provide a highly stable, reliable and efficient signal source at microwave frequencies from 2 to 40 GHz. The low profile and rugged construction provide excellent durability against harsh environmental conditions.

DRO-1500 series is internally voltage regulated to avoid reverse bias, frequency pushing, bias modulation and voltage transients. Mechanical frequency adjustment is provided for desired frequency setting within the bandwidth.
