Classification: CPC H | IPC H

Claim 4:
5. An analog beamforming receiver network comprising a subarray, the subarray including:
a first circuit element configured to receive a radio frequency (RF) signal from a first antenna, frequency down-convert the RF signal received from the first antenna to a first lower frequency (LF) signal, and multiply the first LF signal by a first-element beam forming weight to generate a first-element output signal;
a second circuit element configured to receive the RF signal from a second antenna, frequency down-convert the RF signal received from the second antenna to a second LF signal, delay the second LF signal by a time delay, and multiply the delayed second LF signal by a second-element beam forming weight to generate a second-element output signal; and
a summing circuit configured to sum the first-element output signal and the second-element output signal to generate an output signal of the subarray.
