Abstract: A frequency source with improved phase noise. In one embodiment a phase-locked loop is used as a component of a frequency source and a signal to noise enhancer (SNE) is used to suppress phase noise produced by the phase-locked loop. The signal to noise enhancer is a nonlinear passive device that attenuates low-power signals while transmitting high power signals with little loss. The signal to noise enhancer may be fabricated as a thin film of yttrium iron garnet (YIG) epitaxially grown on a gadolinium gallium garnet (GGG) substrate, the GGG substrate being secured to a microwave transmission line from the input to the output of the signal to noise enhancer, such that the thin film of yttrium iron garnet is close to the transmission line.

Abstract: A feed-forward cancellation system includes a transmitting element and a receiving element. The transmitting element is in electrical communication with a transmitting line. The transmitting element is configured output a transmission signal to the transmitting line. The receiving element is in electrical communication with a receiving line. The receiving element is configured to process a response signal that is generated in response to the transmission signal and that is delivered to the receiving line. At least one antenna is configured to transmit the transmission signal, receive the response signal generated based on the transmission signal, and deliver the response signal to the receiving line. The feed-forward cancellation system further includes an electronic cancellation unit configured to generate a cancellation signal based on the transmission signal. The cancellation signal eliminates saturation from at least one of the response signal and the receiving line.

Abstract: A frequency conversion system with improved performance. In one embodiment an image reject mixer is used to perform frequency conversion providing an initial degree of suppression of the image and local oscillator leakage signals, and a signal to noise enhancer (SNE) is used to further suppress the image and local oscillator signals, the signal to noise enhancer being a nonlinear passive device that attenuates low-power signals while transmitting high power signals with little loss. The signal to noise enhancer may be fabricated as a thin film of yttrium iron garnet (YIG) epitaxially grown on a gadolinium gallium garnet (GGG) substrate, the GGG substrate secured to a microwave transmission line from the input to the output of the signal to noise enhancer, such that the thin film of yttrium iron garnet is close to the transmission line.
