Abstract
The performance of microwave components is sensitive to vibrations to some extent. Among them, microwave cables and connectors, bandpass filters, mechanical phase shifters and some non-linear components are the most sensitive. The local oscillator is one of the prime performance-limiting components in microwave systems ranging from a simple RF receiver to advanced radars. The increasing present and future demand for low acceleration sensitive oscillators, approaching 10-13/g, requires a re-examination of sensitivities of basic non-oscillatory building block components under vibration. The purpose of this paper is to study the performance of an assortment of oscillatory and non-oscillatory microwave components at 10 GHz under vibration. We point out some challenges and provide few tips for accurate measurement of vibration sensitivity of these components. We also study the affect of vibration on the amplitude modulated (AM) noise.Citation
