Abstract
A circuit for amplifying an input signal can comprise a plurality of couplers. A splitting coupler of the plurality of couplers can receive the input signal and a combining coupler of the plurality of couplers can provides an output signal. N number of amplifiers can be included in the circuit to amplify the input signal, wherein N is a non-binary integer greater than one. At least one of the plurality of couplers can comprise a hybrid coupler that has two ports terminated into substantially equal reactances.

A circuit for amplifying an input signal comprising:
- a plurality of couplers, wherein a splitting coupler of the plurality of couplers receives the input signal and a combining coupler of the plurality of couplers provides an output signal;
- and
- N number of amplifiers to amplify the input signal, wherein N is a non-binary integer greater than one;
- wherein at least one of the plurality of couplers comprises a hybrid coupler that has two ports terminated into substantially equal reactances.
A system for amplifying an input signal comprising:
- a signal source to provide the input signal;
- a phase compensating amplifier system comprising:
- N number of amplifiers configured to amplify the input signal, wherein N is a non-binary integer greater than one;
- and
- a plurality of couplers arranged and configured to compensate for a nonlinear insertion phase of the plurality of couplers, wherein at least one of the couplers comprises a hybrid coupler to provide a phase advance of the input signal;
- and
- a load that receives an output signal from the phase compensating amplifier system.
A hybrid coupler comprising:
- a thru port terminated into a first reactance;
- a coupled port terminated into a second reactance, substantially equal to the first reactance;
- an input port to receive an input signal;
- and
- an isolated port to provide an output signal, wherein the output signal has a phase shift relative to the input signal equal to about two times a delay of the thru port of the hybrid coupler minus 90°.
