Abstract
A system, method, and device for RF upconversion is provided. The system can include a laser, a local oscillator, and an RF mixer, an EAM, a photonic filter, and a photodiode. The mixer can receive an LO signal from the local oscillator. The mixer can be configured to mix LO with an IF signal and output a mixed signal. The EAM can receive an optical signal from the laser, receive the mixed signal from the mixer, and be configured to convert the mixed signal into the photonic domain by modulating the optical signal based on the mixed signal to output a modulated optical signal. The photonic filter can receive the modulated optical signal and can be configured to output a filtered optical signal. The photodiode can receive the filtered optical signal and can be configured to convert the filtered optical signal into the RF domain to output upconverted RF output.
