Claim 12:
13. An analog beamforming transmitter network comprising a subarray, the subarray including:
a splitter circuit configured to split an input signal to the subarray into a first-element input signal and a second-element input signal;
a first circuit element configured to multiply the first-element input signal by a first-element beam forming weight to generate a first low frequency (LF) signal, frequency up-convert the first LF signal to a first radio frequency (RF) signal for transmission through a first antenna; and
a second circuit element configured to multiply the second-element input signal by a second-element beam forming weight to generate a second LF signal, delay the second LF signal by a time delay, frequency up-convert the delayed second LF signal to a second RF signal for transmission through a second antenna.
