Exemplary embodiments can address multiple simultaneously received RF signals which beat within receiver electronics at frequencies similar to that of the down converted signals. An RF mixer is disclosed using a photonic circuit arranged to impose the RF signal and the LO signal onto separate optical beams. An arrangement provides a beam carrying the RF signal to a first optical input of a balanced photodiode receiver and another beam carrying the RF and LO signals to a second optical input of the balanced photodiode receiver. Any beat products formed between different RF signals will be cancelled out at the electrical output of the balanced photodiode receiver."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radio frequency mixer implemented with a photonic circuit","description":"A common method of down converting a received RF signal mixes the received RF signal with a LO signal to create a beat signal.
