Fixed frequency synthesizer delivers ultra low phase noise

August 24, 2014 // By Jean-Pierre Joosting
Z-Communications has announced an RoHS compliant fixed frequency synthesizer designated model SFS6864A-LF in the C-band.

This single frequency synthesizer operates at 6864 MHz with a 10 MHz reference and features a typical phase noise of -86 dBc/Hz at the 10 kHz offset.

The SFS6864A-LF is designed to deliver a typical output power of 3 dBm with a VCO voltage supply of 5 Vdc while drawing 35 mA (typical) and a phase locked loop voltage of 3 Vdc while drawing 11 mA (typical). It features a typical 2nd harmonic suppression of -20 dBc and spurious suppression of -65 dBc.

The fixed frequency synthesizer is housed in the company's standard PLL-V12N package measuring 0.6- x 0.6- x 0.13-inches (15.2- x 15.2- x 3.3-mm). It is suitable for automated surface mount assembly and is available in tape and reel packaging.

The device is ideal for satellite communications applications and operates over the industrial temperature range of -40 to 85°C.
