Ultra-small OCVCSOs deliver low noise, power

March 9, 2020  Stephen Law

IQD FREQUENCY PRODUCTS OCVCSO series high frequency Oven Controlled Voltage Controlled SAW Oscillators (OCVCSOs) come in three frequencies of 400MHz, 800MHz and 1.2GHz and are packaged in a 25.4 x 22 x 13.2mm industry standard SMD package. Devices 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. Device’s 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.
