Abstract

The invention provides a microstrip type Lange coupler, and the coupler comprises a substrate, a first short finger line, a first long finger line, a second short finger line, a second long finger line and a first inductor, wherein the two ends of the second short finger line are connected with the two ends of the first short finger line respectively, and the first long finger line is located between the first short finger line and the second short finger line; the two ends of the second long finger line are connected with the two ends of the first long finger line respectively, and the secondlong finger line is located on the side, away from the first long finger line, of the second short finger line. The substrate is provided with an input port, a straight-through port, a coupling portand an isolation port. The first inductor is connected with the first short finger line and the input port. According to the microstrip type Lange coupler, the first inductor is connected with the first short finger line and the input port, so that the return loss of returning to the input port from the straight-through port, the coupling port and the isolation port can be reduced; moreover, the length of the microstrip line can be reduced, so that the size of the microstrip type Lange coupler can be reduced.

Description

technical field [0001] The present application belongs to the technical field of communication equipment, and more specifically relates to a microstrip Lange coupler. Background technique [0002] With the rapid development of modern communication systems, the volume of communication equipment is continuously reduced, and the communication frequency band is constantly developing towards broadband and high-frequency bands. The requirements for communication equipment are getting higher and higher, which promotes channel separation as a key component in communication systems. The development of the coupler in the channel splitter has promoted the development of the coupler in the direction of miniaturization and high reliability. [0003] MMIC (Monolithic Microwave Integrated Circuit, monolithic microwave integrated circuit) passive devices have the advantages of small size, light weight, excellent performance and good consistency, and have good applicability in higher frequen...
