Abstract
RF Monolithics proposes to reduce the vibration sensitivity of the low-noise (1fs target jitter), miniature (25 x 25 x 5 mm3) oscillator (MINO) presently being developed for use in advanced communications and radar systems by Q-DOT, Inc. The MINO willp[rovide the low noise 2.5GHz (nominal) clock waveform for the next generation of ADCs. RF Monolithics is providing microwave resonators and the final packaging configuration for this advanced oscillator and both will be optimized to reduce vibrationsensitivity.The microwave resonator used in the ruggedized MINO will be realized using surface transverse wave (STW) acoustic device technology and will be fabricated on a piezoelectric substrate derived from the langasite (LGS) family of materials. We expect toachieve at least an order of magnitude improvement in both the unloaded Q and the vibration sensitivity of the resonator compared to devices constructed on more conventional quartz substrates. The MINO module will be realized as a ceramic hybrid microwavecircuit, providing both component and interconnect stability for high reliability and low vibration sensitivity.Several resonator and hybrid configurations will be constructed and evaluated. The final configuration of the ruggedized MINO is expected to be added to RFM's line of frequency control products.
