“…The local oscillator is one of the prime performance-limiting components in an RF receiver. However, with increasing demand for low acceleration sensitivity of oscillators in various applications, the sensitivity to vibration of these non-oscillatory components will soon be the limiting factor and thus cannot be ignored (Driscoll & Donovan, 2007). In this section, the performance of some of the nonoscillatory microwave and optical components under vibration is discussed.…”

“…As we have learned from microwave telecommunications in the past, several components in a communication system can cause phase noise degradation in the presence of vibrations, including coaxial cables, cable connectors, or narrowband filters [7]. In this experiment, the focus was on the local oscillator only.…”

“…This makes it impossible to observe transient effects such as polarization rotations [4]. Another important transient impairment is the frequency instability of the local oscillator that can be observed in the presence of mechanical vibrations and has been extensively covered for other communication systems [5]- [7]. However, the stability of typical lasers used in fiber communications has not been commented upon yet.…”

Abstract-Coherent communication systems are largely limited by the laser linewidth of the local oscillator. In addition to phase noise, large frequency deviations can occur if the laser is mechanically vibrated. The detrimental effect of the frequency instability is measured for coherent optical receivers on a typical laser and numerically analyzed for quadrature phase-shift keying and 16-quadrature amplitude modulation using common feed-forward carrier phase recovery algorithms.

“…The resonant frequency of a resonator depends on its dimensions, thus mapping any changes in size to frequency. Vibration also mechanically deforms non-frequency-determining electronic components that then cause phase fluctuations [4], [5]. In general, these effects are more prominent in higher-frequency oscillators, due to increased signal phase sensitivity to mechanical deformation and decreased resonator quality factor.…”

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 nonlinear components are the most sensitive. The local oscillator is one of the prime performance-limiting components in microwave systems ranging from simple RF receivers 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 nonoscillatory building block components under vibration. The purpose of this paper is to study the phase-modulation (PM) noise performance of an assortment of oscillatory and nonoscillatory microwave components under vibration at 10 GHz. We point out some challenges and provide suggestions for accurate measurement of vibration sensitivity of these components. We also study the effect of vibration on the amplitude-modulation (AM) noise.
