L-Band VCO Features Low Second-Harmonic And Phase Noise July 14, 2008
Operating in the L-band from 1560 to 1580 MHz, the CLV1570B-LF voltage-controlled oscillator (VCO) is well-suited for microwave radio applications that require superior second-harmonic suppression and very low phase noise. The device’s tuning voltage range is 0.5 to 4.5 V dc. It has a typical phase noise of –108 dBc/Hz at a 10-kHz offset and a typical tuning sensitivity of 25 MHz/V. Second-harmonic suppression is typically –25 dBc. The VCO uses a 5-V dc supply, drawing 24 mA (typical) over a –40°C to 85°C range. The RoHS-compliant CLV1570B-LF comes in the company’s industry standard MINI package with low shield measuring 0.50” by 0.50” by 0.13”. It is available in tape-and-reel packaging for production requirements. The CLV1570B-LF is also well suited for automated surface-mount assembly and reflow soldering.
