    • A method and a system/circuit for multi-beamforming signal processing are provided. The circuit includes a plurality of basic modules associated with a plurality of transducers (e.g. antenna elements). Each basic module includes first processing stage having a first port operative at a first sampling rates (e.g. for providing signal to/from a respective transducer), a second processing stage having N second ports operative at a second sampling rate (e.g. through which beam-components of the signal are provided thereto/therefrom), and path selector multiplexer module for managing signal coupling between the first and second stages. The first sampling rate is higher than the second sampling rate, and correspondingly the first and second processing stages are configured for introducing to the signals processed thereby time delays of higher and lower temporal resolutions respectively. The first processing stage includes a network of first type time delay channels defining L signal paths providing L respectively different time delays of the higher temporal resolution higher. The second processing stage includes an array of N second type time delay channels connected respectively to the N second ports, each o being operable for shifting a signal communicated therethrough by any number up-to K samples of the second sampling rate. The path selector multiplexer module selectively links any one of the L signal paths of the first stage with any one or more of the N second type time delay channels of the second stage.

    • An apparatus has an array of antennae. Each antenna in the array has a tile circuit including a frequency conversion circuit to generate from an incoming reference signal a local oscillator carrier signal operative as an outgoing reference signal for an adjacent tile circuit. A mixer receives the local oscillator carrier signal and combines it with an antenna signal to produce a frequency converted antenna signal. A matrix of phase shifters and variable gain elements produces a set of frequency converted and phase rotated antenna signals. Analog summers combine the frequency converted and phase rotated antenna signals with user input signals from the adjacent tile circuit for distributed analog beam forming of multiple streams. The user input signals correspond to distinct users tracked by the array of antennae.

    • A phased array includes a laminar substrate having both 1) a plurality of elements forming a patch phased array, and 2) a plurality of integrated circuits. Each integrated circuit is configured to control receipt and transmission of signals by the plurality of elements in the patch phased array. The integrated circuits also are configured to operate the phased array at one or more satellite frequencies — to transmit signals to and/ or receive signals from a satellite. Each integrated circuit physically couples with one corresponding element so that incoming signals are received by the corresponding element in a first polarization, and outgoing signals are transmitted by the corresponding element in a second polarization. The phased array isolates the transmit signals from the receive signals by orienting the first and second polarizations differently.
