摘要
The present invention has developed an asymmetric C-band diphracer using a multi-ball type 3dB coupler (transmitting / receiving terminal) to improve the performance and reduce the size and weight of the conventional symmetric structure, It has its purpose.;In the configuration of the present invention, a part connected to the corrugated horn 2 is a square common waveguide 5, and two asymmetric parallel receiving joints 7a and 7b connected in parallel to the orthogonal plane of the waveguide, Pass filters 8a and 8b are connected to the post-type low-pass filters 10a and 10b and connected to the receiving end porous type 3 dB coupler to constitute the receiving end. The high pass filter 12 is arranged between the stepped waveguide 6 and the orthogonal mode converter 13 and two vertically branched waveguides in the orthogonal mode transducer 13 are connected to the transmitting end porous type 3dB coupler 15 Thereby forming a transmitting end.;According to the present invention, the overall configuration is simple as compared with the conventional diaphragm having a symmetrical structure, thereby reducing the size and weight of the diaphragm, lowering the price, and providing excellent performance.
