Claim 15:
16. A transceiver comprising:
a multiple-channel phasing receiver circuit comprising:
a splitter circuit configured to split a receive signal into a plurality of first signals;
a plurality of single-channel receivers configured to provide a corresponding plurality of first intermediate signals, each single-channel receiver of the plurality of single-channel receivers having:
an input configured to receive a corresponding respective first signal of the plurality of first signals; and
an output configured to provide a corresponding respective first intermediate signal of the plurality of first intermediate signals, wherein the respective first intermediate signal is a function of at least:
the corresponding respective first signal; and
a corresponding respective phase of a first plurality of phases of a local oscillator signal; and

a digital signal processor configured to combine the plurality of first intermediate signals into a single output receive signal;
wherein the first plurality of phases of the local oscillator signal is distributed over π/2 radians; and

a multiple-channel phasing transmitter circuit comprising:
a phasor splitter configured to split a transmit signal into a plurality of second signals;
a plurality of single-channel transmitters configured to provide a corresponding plurality of second intermediate signals, each single-channel transmitter of the plurality of single-channel transmitters having:
an input configured to receive a corresponding respective second signal of the plurality of second signals; and
an output configured to provide a corresponding respective second intermediate signal of the plurality of second intermediate signals, wherein the respective second intermediate signal is a function of at least:
the correspond respective second signal; and
a corresponding respective phase of a second plurality of phases of the local oscillator signal; and

a summing circuit configured to add the plurality of second intermediate signals into a single output transmit signal;
wherein the second plurality of phases of the local oscillator signal is distributed over π/2 radians.
