Abstract

The invention discloses a four-power divider with an LTCC-based S-waveband lumped symmetric structure. The power divider for a reactance network adopts a specific lumped symmetric structure, is formedby three-dimensional placement of lumped parameter elements through multi-layer low-temperature co-fired ceramic technology, and the size of the device is greatly reduced. The four-power divider divides and distributes input signal power into four output ports, and the advantages of small insertion loss, small size, light weight, good output port phase consistency, high isolation degree, high reliability, good electrical performance and good temperature stability, good electrical performance batch consistency, and low cost and allows mass production. The four-power divider can be used as a single component and is suitable for mobile communication and satellite communication such as Beidou navigation systems, and is also suitable for system and devices with high requirements on electric performance, material consistency, thermal mechanical property, temperature stability, manufacturability and anti-interference performance.

Description

technical field [0001] The invention relates to an LTCC-based S-band lumped symmetrical structure four-power splitter, which is suitable for occasions and corresponding applications that have strict requirements on electrical performance, temperature stability and reliability, such as radars in corresponding frequency bands and multi-channel relay communication machines. in the system. Background technique [0002] With the rapid development of mobile communications, the requirements for device performance and size are getting higher and higher. High performance, low cost and miniaturization have become the development trend in the microwave field. In many cutting-edge devices, the microwave frequency bands used today are already quite crowded. In order to solve this problem, the research on equipment in the millimeter-wave band has gradually emerged. With the help of the rapid development of multi-channel multiplexing technology, the multi-channel power The splitter become...
