  • Patent number: 9866267
    Abstract: Devices and methods for providing enhanced diversity reception and cosite cancellation are disclosed. According to one aspect, the subject matter described herein includes a device for providing enhanced diversity reception and cosite cancellation. The device includes a transmit chain connected to a circulator further connected to first antenna and to a combiner. The combiner is connected to anti-cosite circuitry and to first detector. The anti-cosite circuitry is further connected to a secondary antenna. The first detector is further connected to a receive chain.

  • Patent number: 9735758
    Abstract: Analog interference filter devices and methods for isolation of desirable portions of a radio frequency signal. Signal compensation is used to provide desirable center frequency, passband width, ripple, rolloff, stopband and distortion performance. The filter is implemented with passive and/or active components.

  • Patent number: 9450625
    Abstract: Methods, systems, and computer readable media for wideband frequency and bandwidth tunable filtering are disclosed. According to one aspect, the subject matter described herein includes a wideband frequency and bandwidth tunable filter that splits a filter input signal into first and second input signals, modifies the first input signal to produce a first output signal, modifies the second input signal to produce a second output signal having an intermediate frequency response, and combines the first and second output signals while adjusting their relative phases and/or amplitudes to produce a filter output signal with the target frequency response. Adjustment includes splitting the second input signal into third and fourth input signals, which are modified and then combined to produce the second output signal having the intermediate frequency response.
