Abstract:
A system, method, and device for RF upconversion. The system can include a laser, two EAMs, a photonic filter, a photonic service filter, two photodiodes, and a mixer. The first EAM can convert a received RF signal into the photonic domain by modulating an optical signal (received from the laser) based on the received RF signal to output a modulated optical signal. The photonic filter can output a filtered optical signal based on the modulated optical signal to the first photodiode which can output a filtered RF signal in the RF domain. The second EAM can output an LO modulated optical signal based on a received LO to the service filter which can output a filtered LO optical signal to the second photodiode which can output a filtered LO signal in the RF domain. The mixer can mix the filtered RF and LO signals to generate an IF signal.
