A local oscillator produces a microwave frequency source in electrical form. A directly modulated laser receives the first microwave frequency source and produces an optical signal. An optical fiber is used to convey the optical signal from the laser to a photodetector. The photodetector receives a first component of the optical signal and converts the first component of the optical signal to a second microwave frequency source in electrical form. A microwave modulator performs microwave modulation using the second microwave frequency source, and a microwave antenna configured to transmit an output of the first microwave modulator. For MIMO operation, there can be a second microwave modulator. The microwave frequency source can also be conveyed to the second microwave modulator using optical fiber, or the source can be proximate to one of the two microwave modulators, and conveyed to the other of the two microwave modulators using optical fiber."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for photonic distribution of microwave frequency electrical signal for distributed microwave MIMO communications","description":"A microwave transmit system is provided that makes use of optical fiber to convey a microwave frequency source.
