1581-MHz VCO Offers 0.5- To 4.5-V Control Voltage

The CVCO55CC-1581-1581 voltage-controlled oscillator (VCO) from Crystek Corp. operates at 1581 MHz with a control voltage range of 0.5 to 4.5 V. It features a typical phase noise of –120 dBc/Hz at a 10-kHz offset and has excellent linearity, according to the company. Also, its output power typically is +2.5 dBm.

Engineered and manufactured in the United States, the VCO comes in the industry-standard 0.5- by 0.5-in. surface-mount device (SMD) package. Its input voltage is 5 V, with a maximum current consumption of 25 mA. Pulling and pushing are minimized to 1.0 MHz and 1.0 MHz/V, respectively. Second harmonic suppression is –15 dBc typical.

Designed for digital radio equipment, fixed wireless access, satellite communications, basestations, and other applications, the CVCO55CC-1581-1581 costs $18.46 each in volume.
