Z-Communications, Inc. announces a new RoHS compliant Fixed Frequency Synthesizer model SFS3450C-LF in the S-band. The SFS3450C-LF is a preprogrammed synthesizer that is phase locked at 3450 MHz to an external 10 MHz reference oscillator. This low cost PLL features a typical phase noise of -91 and -104dBc/Hz at the 1kHz and 10kHz offsets, respectively.

The SFS3450C-LF is designed to deliver a typical output power of +2dBm while operating off a VCO voltage supply of 5Vdc and drawing 25mA (typical) and a phase locked loop voltage of 3Vdc while drawing 11mA (typical). This Fixed Frequency Synthesizer features a typical 2nd harmonic suppression of -15dBc and spurious suppression of -65dBc. It is housed in Z-COMM’s standard PLL-V12C package measuring 0.6 in. x 0.6 in. x 0.22 in. The SFS3450C-LF is also ideal for automated surface mount assembly and is available in tape and reel packaging.

SFS3450C-LF is an excellent choice for satellite communication applications which require quick and simple integration while demanding high performance over the industrial temperature range of -40 to 85°C.
