ULTRA-LOW PHASE NOISE SAW OSCILLATORS

API Technologies designs and manufactures high-rel SAW Oscillators for today’s space and defense market. API utilizes a low jitter planar SAW which translates to extremely low phase noise performance and exceptionally low accumulated jitter. These high performance SAW Oscillators, in frequencies from 100 MHz to 4000 MHz, also feature high stability and reliability.

Featured Products:

Applications

  • Clocks for communications
  • Test equipment signal sources
  • Clocks for up/down converters
We use a low loss planar SAW device as the frequency controlling element.
