VHF PLO

Description

The VHF PLO is a 25 MHz to 130 MHz fixed frequency rugged OCXO integrated with a low noise phase lock loop circuit and optional x2 multiplier circuit. The integrated assembly can provide fixed output frequencies from 25 MHz to 260 MHz and offers good temperature stability (when free-running), Standard or Premium phase noise options and low g-sensitivity (to 2E-10/g per axis). Frequency dividers are used to prescale the internal VHF oscillator and the external reference frequencies to phase lock at a common lower frequency. The PLL loop bandwidth options are typically ≤5 Hz or ≤60 Hz, but can be configured for optimal performance considering the reference signal provided. The PLO is housed in a 3.5” x 2.5” x 0.8” nickel plated machined aluminum case. An internal voltage regulator is provided for excellent power supply line rejection. Please consult the factory if you need any specifications to be modified to better suit your application.
