    Abstract: A frequency selective limiter (FSL) is provided having a transmission line structure with a tapered width. The FSL includes a magnetic material having first and second opposing surfaces. A first conductor is disposed on the first surface of the magnetic material, where a width of the first conductor decreases from a first end of the FSL to a second end of the FSL along a length of the FSL. Two second conductors are disposed on the second surface of the magnetic material, where a width of a gap between the two second conductors decreases from the first end of the FSL to the second end of the FSL along a length of the FSL. The first conductor and two second conductors form a biplanar waveguide transmission line.

    Abstract: The present disclosure is directed towards a frequency selective limiter having a first magnetic material disposed over a first dielectric material and a strip conductor disposed over the magnetic material. In some embodiments, the frequency selective limiter includes a second magnetic material disposed over the strip conductor and a second dielectric material disposed over the second magnetic material. The first and second dielectric material may have a lower relative permittivity than the first and second magnetic material. In an embodiment, the frequency selective limiter includes a slow wave structure disposed to magnetically couple a magnetic field, produced by electromagnetic energy propagating through the slow wave structure, into the magnetic material.

    Abstract: A frequency conversion circuit having a plurality of N signal channels, each being fed an input signal and a train of pluses having a period T and a duty cycle T/N. Each channel includes: a sampler coupled the input signal and being responsive to sampling signals; and a controllable time delay for producing the train of sampling signals in response to the train of pulses, the time delay imparting a time delay to the pulses in accordance with a time delay command signal fed to the time delay. Each one of the sampling signals is produced by the time delay in each one of the channels with the period T and the duty cycle T/N with the sampling signals in one of the trains of the sampling signals being delayed with respect to the sampling signals in another one of the trains the sampling signals a time T/N.

    Abstract: A transmit drive circuit with high signal to noise and frequency agility. In one embodiment, a transmit circuit includes a digital to analog converter, an amplifier, and a signal to noise enhancer, 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.
