Claim 11:
12. A multiple-channel phasing transmitter comprising:
a phasor splitter configured to split an input signal into a plurality of signals;
a plurality of single-channel transmitters configured to provide a corresponding plurality of intermediate signals, each single-channel transmitter of the plurality of single-channel transmitters having:
an input configured to receive a corresponding respective signal of the plurality of signals; and
an output configured to provide a corresponding respective intermediate signal of the plurality of intermediate signals, wherein the respective intermediate signal is a function of at least:
the corresponding respective signal; and
a corresponding respective phase of a plurality of phases of a local oscillator signal; and

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