Frequency-hopping tuning theory of multicoupler and its realization

The article introduces traditional fixed-frequency multicoupler and its defects through analysis over strong points of frequency-hopping communication and antenna-sharing communication, which presents the advantages of frequency-hopping Multicoupler in a distinctive manner. A proposal focused on frequency-hopping operation for Multicoupler has been in this article designed and put forward, which can be divided into such main units as control unit, filter group, drive circuit of switch matrix, and filter tandem network. The proposal is proved to meet the requirements for Multicoupler to track high-speed frequency-hopping of radios, and to boast such advantages as rapid tandem for cavity filters, high reliability, and compact size needed for the equipment.
