Abstract :
Frequency spectrum conservation and the prevention of interference among 6-gigacycle (gc) microwave systems are shown to be possible when a modified TH system frequency plan is used. Characteristics of the microwave transmitters and receivers used with this plan are discussed. Efficient duplexing of radio-frequency (r-f) equipment uses 3-port circulators and dual polarized antennas. Precautions in the use of these devices are illustrated.
