Assignee: RAYTHEON COMPANY
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 10:
11. A method of modulating a signal comprising:
splitting an input signal into a first divided signal and a second divided signal, the first divided signal and second divided signal being 90° apart in phase;
receiving the first divided signal with first primary windings of center-tapped primary windings;
receiving the second divided signal with second primary windings of the center-tapped primary windings;
transmitting first and second phase shifted output signals with first secondary windings, the first secondary windings being inductively coupled to the first primary windings, the first phase shifted output signal being phase shifted 180° and the second phase shifted output signal being phase shifted 0°;
transmitting third and fourth phase shifted output signals with second secondary windings, the second secondary windings being inductively coupled to the second primary windings, the third phase shifted output signal being phase shifted 270° and the fourth phase shifted output signal being phase shifted 90°;
selectively outputting one of the first, second, third, and fourth output signals, or a combination thereof, as a vector modulated output signal in response to a control signal with a switch configured to receive the first, second, third, and fourth phase shifted output signals.
