摘要： A phased array antenna panel includes a first plurality of antennas, a first radio frequency (RF) front end chip, a second plurality of antennas, a second RF front end chip, and a combiner RF chip. The first and second RE front end chips receive respective first and second input signals from the first and second pluralities of antennas, and produce respective first and second output signals based on the respective first and second input signals. The combiner RE chip can receive the first and second output signals and produce a power combined output signal that is a combination of powers of the first and second output signals. Alternatively, a power combiner can receive the first and second output signals and produce a power combined output signal, and the combiner RF chip can receive the power combined output signal.
