Wide-band right-angle feeding device

Abstract

The invention discloses a broadband rectangle feed which comprises a box body and a direct-current path and a radio frequency path realizing circuit integration / shunting. The radio frequency path comprises a first port connected with a base station end and a second interface connected with an antenna feed system end, a third port used for transmitting direct-current signals is arranged at one end of the direct-current path, and the other end of the direct-current path is connected with the radio frequency path so as to facilitate signals to shunt circuit or integrate circuit, wherein, the first port and the second port are respectively arranged on two mutually vertical surfaces of the box body; the first port and the second port are respectively connected with both poles of a set of cylinder type capacitors in the box body. In the broadband rectangle feed, the first port and the second port are respectively arranged on the two mutually vertical surfaces to form rectangle connection, and additional switchover cables are not necessary to be arranged when the feed is connected with the base station equipment. Therefore, extremely low insertion loss and passive intermodulation can be maintained and production cost and networking cost for communication equipment are both reduced.

Description

【Technical field】 [0001] The invention relates to a wide-band right-angle feeder in the field of mobile communication. 【technical background】 [0002] Please refer to the patent of invention with the announcement number CN 101330302A which the applicant applied on June 19, 2007 and authorized on December 24, 2008. This patent discloses a broadband feeder, which overcomes many deficiencies in the prior art. By using a straight-through capacitive coupling design between the combined port and the radio frequency port, the feeder tends to be miniaturized and at the same time obtains Relatively good electrical effect (please refer to the announcement text of this patent for details). [0003] In the existing feeder including the above-mentioned prior application, the combination port and the radio frequency port are connected by a straight-through structure, so that the two ports are on the same straight line. However, in the existing mobile communication base station equipment...

Problems solved by technology

Therefore, due to the feeder in the prior art, due to its straight-through structure, it is necessary to add an adapter cable when it is installed on the base station equipment, which will increase the insertion loss of the entire path and cause the deterioration of passive intermodulation , affects the receiving performance of the base station equipment, and of course increases the cost of building the station
