Fixed frequency synthesizer delivers low phase noise

October 20, 2014 // By Jean-Pierre Joosting
Z-Communications has announced an RoHS compliant fixed frequency synthesizer, designated model SFS11600H-LF.

The high performance synthesizer is designed to generate an output signal at 11.6 GHz while being fixed to an external 100 MHz reference oscillator. The X-Band PLL features phase noise performance of -98 dBc/Hz at 1 kHz and -103 dBc/Hz at 10 kHz offset.

The SFS11600H-LF is designed to deliver a nominal output power of 0 dBm into a 50Ω load and operates with a VCO voltage supply of 5 Vdc while drawing 85 mA (typical) and a phase locked loop voltage of 3.3 Vdc while drawing 40 mA (typical). This low noise fixed frequency synthesizer features harmonic suppression of -30 dBc and spurious suppression of -65 dBc.

The synthesizer is housed in the company's standard SFS-L1 package measuring 2.54- x 2.54- x 0.56-cm (1.0- x 1.0- x 0.22-inches. The SFS11600H-LF is also ideal for automated surface mount assembly and is available in tape and reel packaging.

The SFS11600H-LF is an ideal choice for test instrumentation, radar equipment and various other applications, and is guaranteed over the industrial temperature range of -40 to 85°C.
