Classification: CPC H | IPC H

Claim 9:
10. A circuit for wireless signal reception comprising a switching network having:
M switches;
N inputs connected to the M switches and configured to connect to N antenna sub-arrays; and
K outputs connected to the M switches and configured to connect to K amplifiers, where M is greater than N and K and M, N, and K are integers greater than 1, and wherein the M switches are configured to route a signal from a selected input of the N inputs to a selected output of the K outputs,
further comprising a receiver network having:
a first amplifier having a first input to receive a first wireless communication signal from a first of the K outputs;
a first mixer or synthesizer connected to a first output of the first amplifier;
a second mixer or synthesizer connected to a second output of the first amplifier;
a second amplifier having a second input to receive a second wireless communication signal from a second of the K outputs;
a third mixer or synthesizer connected to a third output of the second amplifier; and
a fourth mixer or synthesizer connected to a fourth output of the second amplifier, wherein an output of the first mixer or synthesizer and an output of the third mixer or synthesizer are connected to a first node and an output of the second mixer or synthesizer and an output of the fourth mixer or synthesizer are connected to a second node, wherein the circuit further comprises:
a third amplifier having a third input to receive a third wireless communication signal;
a fifth mixer or synthesizer connected to a fifth output of the third amplifier;
a sixth mixer or synthesizer connected to a sixth output of the third amplifier;
a fourth amplifier having a fourth input to receive a fourth wireless communication signal;
a seventh mixer or synthesizer connected to a seventh output of the fourth amplifier; and
an eighth mixer or synthesizer connected to an eighth output of the fourth amplifier, wherein an output of the fifth mixer or synthesizer and an output of the seventh mixer or synthesizer are connected to a third node and an output of the sixth mixer or synthesizer and an output of the eighth mixer or synthesizer are connected to a fourth node.
