Multi-Band Microwave Optics Frequency Converter for Satellite Transmitter

Promising telecommunication satellites located in the geostationary orbit of the Earth require the development of radio electronic communication facilities in the frequency range up to 40 GHz for receiving, routing and retransmitting dozens of radio frequency signals through its channels. The concept of an analog frequency converter using microwave photonic technologies to support broadband, noise-protected and flexible transmission of radio signals has been proposed. The device under consideration has a radiophotonic core with radio frequency input and output sections, which is used for frequency conversion and switching of radio channels. The microwave photonic solution favourably differs from radio-frequency realizations thanks to a wide information frequency band, high noise immunity, radiation firmness, economy of weight and volume of useful load of the satellite that allows to provide for perspective telecommunication repeaters reliability and firmness to influence of factors of space environment.
