Z-Communications have announced a new RoHS compliant VCO (Voltage-Controlled Oscillator) model CRO2781A-LF in S-band. The CRO2781A-LF VCO, available from RF Parts Australia , operates at 2780 MHz with a tuning voltage range of 0.5 to 4.5 Vdc. This VCO features a typical phase noise of -115 dBc/Hz@10 KHz offset and a typical tuning sensitivity of 9 MHz/V.
The CRO2781A-LF VCO is designed to deliver a typical output power of 7.5 dBm at 5 Vdc supply while drawing 19 mA (typical) over the temperature range of -40º to 85º C. This VCO features typical second harmonic suppression of -18 dBc and comes in Mini-16 package measuring 0.5 in. x 0.5 in. x 0.22 in. It is available in tape and reel packaging for production requirements. The CRO2781A-LF VCO is also suitable for automated surface mount assembly and reflow. The CRO2781A-LF VCO is suitable for microwave radio and satellite communication applications that require low phase noise performance.
