Low-Noise L-Band VCO comes in 0.5 x 0.5 x 0.22 in. package.

Press Release Summary:




Operating at 1,878–1,879 MHz with 1–4 Vdc tuning voltage range, ceramic resonator-based CRO1878A-LF features SSB spectral purity of -138 dBc/Hz @ 100 kHz offset and operates with average tuning sensitivity of 5 MHz/V. RoHS-compliant VCO delivers 4±2 dBm of output power into 50 Ω load while operating off 5 Vdc supply and drawing 25 mA typ. Operating from -40 to 85°C, low-noice VCO pushes <0.5 MHz/V and pulls <0.5 MHz with 12 dB return loss. Typ second harmonic suppression is -20 dBc.

VCO: CRO1878A-LF Features Remarkable Low Phase Noise Performance in the L-Band



Z-Communications, Inc. announces a new RoHS compliant VCO (Voltage Controlled Oscillator) model CRO1878A-LF. The ceramic resonator based CRO1878A-LF operates at 1878 to 1879 MHz with a tuning voltage range of 1 to 4 Vdc. This high performance VCO features remarkable SSB spectral purity of -138 dBc/Hz @ 100 kHz offset and operates with an average tuning sensitivity of 5 MHz/V.



The CRO1878A-LF is designed to deliver 4±2 dBm of output power into a 50Ω load while operating off a 5 Vdc supply and drawing typically 25 mA of current. This low noise VCO operates over the extended commercial temperature range of -40 to 85°C is further enhanced by pushing less than 0.5 MHz/V and pulling less than 0.5 MHz with a 12 dB return loss. The CRO1878A-LF features typical second harmonic suppression of -20 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 CRO1878A-LF is well suited for microwave radio equipment and satellite communication applications that require low phase noise performance. Additional specifications for this product can be found on-line at: www.zcomm.com
