Patent ID: 7274328

Claim:
A system for transmitting and receiving a plurality of radio frequency signals, comprising: an array system comprising one or more active electronically scanned arrays, the array system comprising: a receive portion comprising a first number of receive elements, a receive element operable to receive a receive signal; and a transmit-receive portion disposed adjacent the receive portion, the transmit-receive portion comprising a second number of transmit-receive elements, the transmit-receive elements having a transmit element power and operable to transmit a transmit signal or to receive a receive signal, the transmit-receive elements comprising: a plurality of monolithic microwave integrated circuit power amplifiers; and a low-loss miniature combiner operable to couple an output signal of the power amplifiers into the transmit signal; a signal processing system operable to: receive the receive signal from the receive elements; process the receive signal; process the transmit signal; and provide the transmit signal to the transmit-receive elements; and a beam forming system operable to generate a plurality of receive beams associated with the receive elements, a receive beam having a receive beam beamwidth that is less than a transmit beam beamwidth of a transmit beam associated with the transmit-receive elements.
