Phase Locked Oscillators
Phase locked oscillators (PLO) utilize state-of-the-art planar circuits, three-terminal devices and dielectric resonator technology to generate high-quality microwave signals at lower frequencies. Frequency multipliers, amplifiers and filters are used to extend the low frequencies for higher frequency requirements. The standard offering covers the frequency range of 2 to 110 GHz and provides both internal and external reference options. The frequency stability and phase noise are dependent on the oscillator reference type.
