Abstract: A phased array radar system includes a first input signal source configured to generate a first input signal (e.g., a clock signal), and a second input signal source configured to generate a second input signal (e.g., a local oscillator signal). A multiplexer is operatively connected to the first and second input signal sources, and is configured to selectively route the first and second input signals onto a single output channel. At least one signal dividing device is operatively connected to the single output channel, and is configured to generate a plurality of output signals from a signal received from the signal multiplexer. A plurality of signal demultiplexers are also provided, with each demultiplexer responsive to one of the plurality of output signals for routing the output signal to one of a plurality of output channels. A plurality of radar receivers and/or exciters are operatively connected to the plurality of output channels of the plurality of multiplexers.

Abstract: An oscillator circuit including a microelectromechanical system (MEMS) resonator is provided. The circuit includes a surface acoustic wave (SAW) resonator having a first input transducer responsive to a first input signal for transducing the first input signal into mechanical motion of a substrate material of the resonator, a second input transducer responsive to a second input signal for transducing the second input signal into mechanical motion of the substrate material, and a first output transducer configured to transduce the mechanical motion of the substrate material of the resonator into an output electrical signal. A feedback loop is provided and configured to generate the second input signal, wherein the second input signal is indicative of a detected phase error of the output of the resonator.
