ABLNO Series is designed with High “Q”, 3rd Overtone Crystal Resonators, enabling exceptional close-tothe-carrier phase noise and wide-band jitter, ideally suited for noise sensitive applications. ABLNO
oscillators in VCXO configuration provide sufficient frequency pull-ability to accommodate re-tuning of the
oscillators to precise carrier frequency, over a 10-year product life. ABLNO oscillators are 100% tested for
Phase Noise compliance at room temperature

In this example, the Ka-Band Up-Converter would greatly benefit from the Ultra Low Phase Noise
performance of the ABLNO reference oscillator at 100MHz; yielding a much cleaner up-converted
