Z-Communications, represented by RF Parts Australia , announce a new RoHS compliant fixed frequency synthesizer model SFS1685A-LF in L-band. The SFS1685A-LF is a single frequency synthesiser that operates at 1685MHz. This synthesiser features a typical phase noise of -106dBc/Hz at 10kHz offset and a typical sideband spurs of -80dBc.
The SFS1685A-LF is designed to deliver a typical output power of 6dBm with a VCO voltage supply of 5V DC while drawing 31mA and a phase locked loop voltage of 3V DC while drawing 9mA over the temperature range of -40ºC to 85º C. This fixed frequency synthesiser features typical 2nd harmonic suppression of -25dBc and comes in Z-Comm’s PLL-V12N package with low shield measuring 0.60 inches x 0.60 inches x 0.13 inches.
The SFS1685A-LF single frequency synthesiser is available in tape and reel packaging for production requirements. The SFS1685A-LF is also suitable for automated surface mount assembly and reflow. The SFS1685A-LF is suitable for satellite communication and GPS applications that require low phase noise performance.
