THE DOUBLE-BALANCED MIXER USING BRANCH-LINE AND RING-HYBRID

摘要

1. the art that the invention defined in the claims; The invention will about double balanced mixer with a branch line and a ring hybrid.; 2. The invention attempts to solve the technical challenges; The present invention is available for easy implementation by forming respectively by using the branch line microstrip hybrid and the ring hybrid the LO balun and RF balun constituting the double-balanced mixer as well as with a so as to have the characteristics of broadband, the branch line and a ring hybrid that aims to provide a double-balanced mixer.; 3. Resolution of the subject matter of the invention,; The present invention, local oscillator (Local Oscillator; LO) baluns and a radio signal; in a double-balanced mixer is configured to include (Radio Frequency RF) balun, the local oscillator balun is formed by using a branch-line microstrip hybrid, the wireless signal balun is also being formed by using a ring, it characterized hybrid.; 4, an important purpose of the invention; The invention yiyongdoem communication relay system or the like.
