A compact oscillator tunes from 5580 to 5685 MHz with low phase noise and low harmonic content.
Designed for communications applications, the model CVCO55CXT-5580-5685 coaxial resonator oscillator (CRO) operates from 5580 to 5685 MHz with low harmonic distortion. It consists of a coaxial-based voltage-controlled oscillator (VCO) with an internal frequency doubler. The proprietary doubling circuitry controls harmonic generation to contribute to the CRO’s excellent spectral purity, with low phase noise and low current consumption during normal operation. Pushing and pulling are controlled to 1.5 MHz/V and 0.5 MHz, respectively, with typical second-harmonic suppression of -30 dBc. The model CVCO55CXT-5580-5685 CRO covers its frequency range with a tuning voltage range of +0.3 to +4.7 VDC. The coaxial VCO features a typical phase noise of -102 dBc/Hz offset 10 kHz from the carrier. It provides 0-dBm typical output power (+3 dBm maximum) into a 50-Ω load with a +5-VDC supply and maximum current consumption of 30 mA. The CRO, which is suitable for applications in digital radio equipment, fixed wireless access, and satellite communications (satcom) systems, is housed in an industry-standard 0.5 x 0.5 in. package. It has an operating temperature range of -40 to +85°C.
