Abstract

Stable local oscillators with low phase noise are extremely important elements in high performance military communication and navigation systems. We present the development of compact UHF-band frequency sources capable of maintaining low phase noise under high accelerations or vibrations and over a wide temperature range for handheld portable systems. We also explored nonlinearity in MEMS resonators and attempted to use nonlinear dynamics to enhance phase noise performance. Using the quartz MEMS technology, we have thus far demonstrated a 645 MHz Pierce oscillator with -113 dBc/Hz phase noise at 1 kHz offset with acceleration sensitivity of 5x10^-10/g. The controlled oscillation of a nonlinear Duffing resonator in a closed-loop system with improved phase noise is described.
