Abstract:
A method for phased array tapering includes setting a gain at a phase-invariant variable gain amplifier in each of a plurality of front-ends of a phased array transceiver to perform tapering of beam pattern side lobes. A resistance in the phase-invariant variable gain amplifier is set to provide a phase shift that is independent of gain.
