IQD Frequency Products has launched a range of high frequency Oven Controlled Voltage Controlled SAW Oscillators (OCVCSOs). Three frequencies are currently available in the OCVCSO series, 400MHz, 800MHz and 1.2GHz and they are packaged in a 25.4x22x13.2mm industry standard SMD package.

These OCVCSOs have a noise floor of 10dB to 15dB lower than an OCXO at the same frequency, enabling a much improved phase noise performance for applications such as radar detection systems. The 400MHz OCVCSO frequency is generated from a fundamental high-Q SAW resonator, whereas the 800MHz and 1.2GHz are generated using high frequency fundamental SAW resonator with a low noise frequency doubler. 

Multiplying the frequency only once enables superior phase noise performance, down to -168dBc/Hz at the floor level and jitter between 10kHz to 100MHz of <10fs. The 400MHz OCVCSO being based on a fundamental frequency has a phase noise performance of -174dBc/Hz at the floor level and jitter of <5fs.

With stabilities down to ±2ppm over an operating temperature range of zero to +50°C and ageing of ±6ppm max over ten years these new lightweight OCVCSOs, weighing only eight grams, are well suited not only for radar but also simulators, communication systems and unmanned aerial vehicles (UAVs). 

The OCVCSO operates from a five volt supply with power consumption of between 0.8 to 1W, has a 50Ω sine output and a voltage control option, which enables the frequency to be pulled by a minimum of ±6ppm.
