Fixed frequency synthesizer features integrated reference

May 09, 2016 // By Jean-Pierre Joosting
RoHS compliant, the fixed frequency phase locked loop model RFS5900A-LF from Z-Communications is a fully integrated synthesizer operating at 5900 MHz, which is phase locked to a 10 MHz reference with a stability of ±2.5ppm.

This low cost PLL features a typical phase noise of -80 dBc/Hz, -85 dBc/Hz, and -103 dBc/Hz at the 1 kHz, 10 kHz and 100 kHz offsets, respectively.
 
The RFS5900A-LF is designed to deliver an output power of 3۬±2 dBm while operating off a VCO voltage supply of 5Vdc and drawing 35mA and a phase locked loop voltage of 3Vdc while drawing 15mA. This product features a 2nd harmonic suppression of -25 dBc and spurious suppression of -65 dBc. It is housed in the company's standard PLL-V12N package measuring 0.6- x 0.6- x 0.13-inches. The RFS5900A-LF is also ideal for automated surface mount assembly and is available in tape and reel packaging.
 
The RFS5900A-LF allows for simple design implementation making it a great choice for quick product rollouts, and is well suited for satellite communications and radar applications requiring operation over the temperature range of -30 to 70°C.
