Model SFS4000C-LF is a RoHS-compliant frequency synthesizer for satellite-communications (satcom) and test applications. The fixed-frequency unit is phase locked at 4 GHz using a 10-MHz reference oscillator. The coaxial synthesizer delivers 0-dBm output power and exhibits phase noise of typically -102 dBc/Hz offset 10 kHz from the carrier with typical spurious content of -65 dBc. Second-harmonic levels are typically -15 dBc. The frequency source, which is supplied in a PLL-V12C package measuring 0.60 in. x 0.60 in. x 0.22 in., consists of a voltage-controlled oscillator (VCO) with power consumption of 30 mA at +5 VDC, as well as a phase-lock-loop (PLL) chip with power consumption of 11 mA at +3.3 VDC. It is designed for operating temperatures from -25 to +90°C.
