Radio frequency distribution system (RFDS) for cosite electromagnetic compatibility

This paper describes the development of a patented broadband antenna and radio frequency (RF) distribution system for frequency hopping (FH) systems. The system avoids cosite electromagnetic interference (EMI) problems. The architecture is based on the use of linear comb filter banks in contrast with the traditional diode switching, to provide RF distribution for FH, single channel, and wideband waveforms.
