Abstract
A phase control block for combining signals from a phased array antenna includes a phase shifter for generating a phase shifted signal; a phase switch connected to the phase shifter having a first state wherein the phase switch connects a first signal to a switched signal output and a second signal to the phase shifter; and a signal summing device connected to the phase shifter for generating an output that is a sum of the switched signal output and the phase shifted signal.
