VCO Uses Little Power

Measuring 0.30'' x 0.30'' x 0.08'' and suited for fixed cellular terminals, the SMV1440L voltage-control oscillator operates over a -40°C to 85°C temperature range, generates frequencies between 1,380 and 1,500 MHz within 0 to 3 Vdc of control voltage. The device is said to exhibit a clean spectral signal of -93 dBc/Hz (typ.) at 10 kHz from the carrier and -117 dBc/Hz at 100 kHz from the carrier. The second harmonic is attenuated to better than -15 dBc. The VCO operates from a 3 Vdc source while drawing less than 13 mA and provides the end user nominally 0 ±3 dBm of output power into a 50W load. The pulling spec for SMV1440L is less than 5 MHz/V with a 14 dB return loss, any phase, while pushing is less than 3 MHz within a 5% change of the supply voltage. More details are available from Z COMMUNICATIONS INC., San Diego, CA. (858) 621-2700.
