Z-Communications, Inc. announces a new RoHS compliant VCO (Voltage Controlled Oscillator) model CRO2273B-LF. The CRO2273B-LF operates at 2265 to 2280 MHz with a tuning voltage range of 0.5 to 4.5 Vdc. This high performance VCO features a spectrally clean signal of -115 dBc/Hz @ 10 kHz offset and covers the band with a typical tuning sensitivity of 4 MHz/V.

The CRO2273B-LF is designed to deliver +3 dBm of nominal output power into a 50Ω load while operating off a 5 Vdc supply and drawing typically 20 mA of current. This low noise VCO operates over the extended commercial temperature range of -40 to 85ºC. The CRO2273B-LF features typical second harmonic suppression of -15 dBc and comes in Z-Comm’s standard, MINI-16-SM package measuring 0.5 in. x 0.5 in. x 0.22 in. It is available in tape and reel packaging for production requirements making it ideal for automated surface mount assembly and reflow.

The CRO2273B-LF is well suited for microwave radio and basestation applications that require low phase noise performance.
