Z-Communications, Inc. announces a new RoHS compliant fixed frequency phase locked loop model RFS1090A-LF in the L-band. The RFS1090A-LF is a fully integrated synthesizer operating at 1090MHz which is phase locked to an internal 10MHz reference with a stability of ±2.5ppm. This low cost PLL features a typical phase noise of -93dBc/Hz, -98dBc/Hz, and -118dBc/Hz at the 1kHz, 10kHz and 100kHz offsets, respectively.

The RFS1090A-LF is designed to deliver an output power of 3۬dBm while operating off a VCO voltage supply of 5Vdc and drawing 35mA and a phase locked loop voltage of 3Vdc while drawing 10mA. This unmatched product features a 2nd harmonic suppression of -20dBc and spurious suppression of -62dBc. It is housed in Z-COMM’s standard PLL-V12N package measuring 0.6 in. x 0.6 in. x 0.13 in. The RFS1090A-LF is also ideal for automated surface mount assembly and is available in tape and reel packaging.

The RFS1090A-LF allows for simple design implementation making it a great choice for quick product rollouts, and is well suited for test instrumentation and clock sources requiring operation over the temperature range of -40 to 85°C.
