The RFS1090A-LF is a Fixed Frequency Synthesizer Module that is phase locked at 1090 MHz to an external 10 MHz reference oscillator with a stability of ±2.5ppm. This low cost PLL features a phase noise of -93 dBc/Hz, -98 dBc/Hz, and -118 dBc/Hz at the 1 kHz, 10 kHz and 100 kHz offsets, respectively. It delivers an output power of 3 dBm and requires a supply voltage of 5 Vdc while drawing 35 mA of current and a phase locked loop voltage of 3Vdc while drawing 10mA of current. This synthesizer has a 2nd harmonic suppression of -20 dBc and spurious suppression of -62 dBc. The PLL is available in a package that measures 0.6 x 0.6 x 0.13 inches and is well suited for test instrumentation and clock sources requiring operation over a temperature range from -40 to 85°C.
