摘要： The present invention is directed to a highly-integrated MEMS-based miniaturized transceiver. The transceiver utilizes a low band front-end to direct sample low band signals and a high band front-end to translate high band signals that cannot be directly sampled to low band before low band front-end processing. The low band front-end comprises an array of High-Q MEMS (microelectromechanical systems)-based filters/resonators separated by isolation amplifiers in selectable cascade with narrower bandwidth filters. Dynamic tuning ability is provided through the isolation amplifiers and the sample frequency of the analog-to-digital converter. This architecture is amenable to monolithic fabrication. The input frequency range is scalable with analog-to-digital conversion sampling rate improvements. Re-utilization of filters is spatially efficient and cost effective. Tuning time is limited only by the analog-to-digital conversion and digital signal processing, not synthesizer settling times. This architecture eliminates major sources of traditional intermodulation distortion and reduces complex hardware, increasing reliability.

摘要： A method (100) of providing a time delay to a signal utilizing a surface acoustic wave ladder filter includes a first step (102) of providing a piezoelectric substrate. A second step (104) includes disposing series and shunt coupled surface acoustic wave transducers in a ladder configuration on the substrate with each of the transducers having an associated aperture and an associated number of interdigital electrode elements. A third step (106) includes configuring the associated aperture and an associated number of interdigital electrode elements for each surface acoustic wave transducer for maximum phase linearity of the ladder filter and uniform group delay response from the ladder filter. A fourth step (108) includes adjusting the number of transducers in the ladder filter to provide a desired average group delay. Subsequently passing a signal through the ladder filter will delay the signal by a time equal to the group delay.
