Fixed frequency L-band synthesiser features low phase noise

Z-Communications has released a new RoHS compliant fixed frequency synthesiser in L-band. The SFS1900A-LF is a single frequency synthesiser that operates at 1900 MHz.

This synthesiser features a typical phase noise of -98 dBc/Hz at 10 KHz offset and typical sideband spurs of -70 dBc.

The SFS1900A-LF is designed to deliver a typical output power of 0 dBm with a VCO voltage supply of 5 Vdc while drawing 25 mA (typical), as well as a phase locked loop voltage of 3.3 Vdc while drawing 10 mA (typical) over the temperature range of -40º to 85ºC.

It features typical 2nd harmonic suppression of -20 dBc and comes in Z-Comm's industry standard PLL-V12N package measuring 0.60 in. x 0.60 in. x 0.13 in. It is available in tape and reel packaging for production requirements, and is ideal for automated surface mount assembly and reflow.

SFS1900A-LF is well suited for point to point and satellite communication applications that require low phase noise performance.
