Z-Communications Inc. announces the release of a new breakthrough model of a coaxial resonator-based voltage-controlled oscillator (VCO) in the UHF-band that is RoHS compliant. The new model, ZRO0743B2LF, which is the first VCO of an exciting new series of products in development by Z-COMM, operates from 738 to 748 MHz with a tuning voltage range of 0to 6 VDC. This VCO features an excellent typical phase noise of -131 dBc/Hz at 10 kHz offset and a typical tuning sensitivity of 2 MHz/V.

The ZRO0743B2LF is designed to deliver a typical output power of 9 dBm at 8 VDC supply while drawing 23 mA (typical) over the temperature range of -40° to 85°C. The ZRO0743B2LF has a typical phase noise value of -104 dBc/Hz at 1 KHz offset and -151 dBc/Hz at 100 KHz offset. This VCO features typical 2nd harmonic suppression of -20 dBc and comes in Z-COMM’s newly developed ZMX-14-SM package, measuring 0.75" x 0.75" x 0.22". It is available in tape and reel packaging for production requirements. The ZRO0743B2LF is also ideal for automated surface-mount assembly and reflow assembly process.
