COUPLER HAVING STRUCTURE OF MULTI-AIRSTRIP LINE AND APPARATUS FOR DISTRIBUTING AND COUPLING RF SIGNALS USING THE SAME

摘要

PURPOSE: A coupler having a structure of a multi-airstrip line and an apparatus for distributing and coupling RF signals using the same are provided to improve a passive intermodulation characteristic by using a coupling structure. CONSTITUTION: A coupler having a structure of a multi-airstrip line includes a feeding connector(111), a plurality of feeding connectors(121-124), and a main body. The feeding connector(111) is connected to a transmission amplifier and a reception amplifier. The plural feeding connectors(121-124) are connected to a plurality of antennas. The main body is formed with a housing(131) and a cover(141). The feeding connector(111) is installed at one side of the housing(131). The plural feeding connectors(121-124) are installed at the one side of the housing(131). A plurality of metal airstrip lines(161-163) and a main metal airstrip line(151) are formed at the main body.
