PLO-4200 design incorporates a low noise SC-cut VCXO to be locked to
10MHz to offer the best phase noise performance achievable. Phase Locked Dielectric Resonator Oscillator (PLDRO) utilizes state-of-the-art MIC and SMT to provide crystal stability at microwave frequencies up to 50 GHz. The low profile and rugged construction provide excellent durability against harsh environmental conditions. This model works with external reference of 10 MHz.
