Abstract:
Methods and systems for phased array tapering include setting a gain at a phase-invariant variable gain amplifier in each of a set of front-ends of a phased array transceiver, to perform tapering of beam pattern side lobes. Setting the gain includes setting a first gain at a first stage of the phase-invariant variable gain amplifier and setting a second gain at a second stage of the phase-invariant variable gain amplifier. A dependency of a phase shift of the first stage on the gain of the first stage is equal to and opposite a dependency of a phase shift of the second stage on the gain of the second stage.
