The HF LO Series oscillator is comprised of a VHF frequency OCXO and the necessary dividers to scale down the frequency to produce a fixed output between 1 MHz and 25 MHz. The result is a stable HF frequency oscillator with excellent phase noise performance under vibration. The small lightweight package (1.5” x 1.5” x 0.5”) makes this unit well suited for airborne and mobile applications where good dynamic performance is required. A low noise voltage regulator is included to minimize power supply line related spurious signals. Please contact technical staff to discuss custom requirements.
