  • Publication number: 20210211162
    Abstract: A general-purpose integrated circuit capable of scaling to meet the requirements of a beamforming system for a wide range of applications and benefit from economies of scale is disclosed. The integrated circuit includes a delay and phase correcting engine in order to reference the incoming data to a common array center and steering direction. It also includes a frequency channelization engine to perform phase-shift beamforming tasks effectively and/or frequency channelize the output data stream. A flexible reconfigurable routing logic can be included, which allows a multiplicity of operation modes, and generates a multiplicity of linear combinations of the input and internally generated data streams.

  • Patent number: 10559885
    Abstract: A TEM line to double-ridged waveguide launcher and horn antenna are disclosed. The launcher uses multiple probes or one or more wide-aspect probes across the ridge gap to minimize spreading inductance and a TEM combiner or matching taper to match the impedance of the probes over a broad bandwidth. The horn uses a power-law scaling of gap height relative to the other dimensions of the horn's taper in order to provide a monotonic decrease of cutoff frequencies in all high-order modes. Both of these techniques permit the implementation of ultra-wideband designs at high frequencies where fabrication tolerances are most difficult to meet.

  • Patent number: 10530321
    Abstract: Reflectionless electronic filters, as well as a method for designing such filters is disclosed, along with a method of realizing critical subcircuits within those filters that mimic the behavior of tee- and pi-networks having negative elements, though the critical subcircuits themselves are entirely passive. This allows a much broader range of transmission responses to be realized in reflectionless form than in the prior art, and especially with lower ripple factor for deeper rejection in equal-ripple Chebyshev responses. Reflectionless filters preferably function by absorbing the stop-band portion of the spectrum rather than reflecting it back to the source, which has significant advantages in many different applications.

  • Patent number: 10516378
    Abstract: Reflectionless low-pass, high-pass, band-pass, band-stop, all-pass, all-stop, and multi-band filters, as well as a method for designing such filters is disclosed, along with a method of enhancing the performance of such filters through the use of unmatched sub-networks to realize an optimal frequency response, such as the Chebyshev equal-ripple response. These filters preferably function by absorbing the stop-band portion of the spectrum rather than reflecting it back to the source, which has significant advantages in many different applications. The unmatched sub-networks preferably offer additional degrees of freedom by which element values can be assigned to realize improved cutoff sharpness, stop-band rejection, or other measures of performance.

The methods comprise filtering the bandpass signal with a bandpass filter, generating the real and imaginary parts of the complex analytic signal with a quadrature hybrid, determining the amplitude of the complex analytic signal by adding an even power-law transform of the real and imaginary parts of the complex analytic signal, and determining the phase of the complex analytic signal by comparing the real and imaginary parts of the complex analytic signal to zero and comparing an even power-law transform of the real and imaginary parts of the complex analytic signal to each other. Analog to digital converters and methods of converting complex analytic signals to digital signals are also disclosed.

  • Patent number: 10277189
    Abstract: Reflectionless transmission line filters, as well as a method for designing such filters is disclosed. These filters preferably function by absorbing the stop-band portion of the spectrum rather than reflecting it back to the source, which has significant advantages in many different applications. The insertion of additional transmission line sections that change the phase response of the circuit without altering the amplitude response preferably allows follow-up transmission line identities to be applied in order to arrive at a more easily manufacturable filter topology. This facilitates their application over a higher frequency range the solely lumped-element circuits.
