The CVCO55CC-1290-1310 from Crystek Corporation is a Coaxial Resonator Oscillator (CRO) that operates from 1290 to 1310 MHz. This CRO has a phase noise of -166 dBc/Hz @10 MHz offset and provides a 2nd harmonics suppression of -15 dBc. It requires a tuning voltage from 0.5 V to 4.5 V and has a modulation sensitivity of 5 MHz/V. This oscillator requires a DC supply of 5 V and consumes less than 36 mA of current. It is available in a surface-mount package that measures 12.7 x 12.7 mm and is ideal for use in base stations, satellite communication systems, digital radio equipment, and fixed wireless access (FWA) applications.
