Most RF systems rely on the precision generation of local oscillator frequencies.  This is achieved using phase locked synthesizers.  These synthesizers may also provide special functions like frequency chirps, phase and frequency modulation.  Depending on the application, we can provide varying levels of frequency precision – from low cost quartz oscillators to atomic references that yield frequency precision better that 10-12.   Moreover, we can provide low phase noise solutions such as dielectric resonator phase locked oscillators.
