Abstract
One embodiment provides a broadband signal source. The broadband signal source includes a number, n, signal paths and a combiner circuitry. Each signal path, i, includes a programmable phase shifter circuitry, an amplifier circuitry and a harmonic generation circuitry. The programmable phase shifter circuitry is configured to phase shift a path input signal by a respective phase angle, θ. The path input signal corresponds to a source input signal having a fundamental frequency, f, and an input signal bandwidth. The amplifier circuitry is configured to amplify the phase shifted path input signal. The harmonic generation circuitry is configured to generate a path output signal including a plurality of harmonics of the amplified phase shifted path input signal. The combiner circuitry is configured to combine the number, n, path output signals to produce a broadband output signal having an output signal center frequency greater than the input signal fundamental frequency and an output signal bandwidth greater than the input signal bandwidth.
