Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] We know that LTCC technology is a kind of multilayer wiring substrate technology in MCM. Due to the direct assembly of bare chips on the LTCC multi-layer wiring substrate, the assembly density is greatly improved, the frequency characteristics and transmission speed are improved. LTCC technology allows the chips to be closer and the interconnection lines to be shortened. The package size also solves the problems of crosstalk noise, stray inductance, stray capacitive coupling, and electromagnetic field radiation. While maintaining the original electrical properties of the components as much a...

Abstract

The invention discloses an LTCC delay line assembly which comprises five medium layers arranged from top to bottom. The medium layers are separated by metal layers. The first medium layer comprises a micro-strip layer, a first micro-strip medium layer, a cavity metal bottom layer and a second micro-strip medium layer which are arranged from top to bottom. Belt-shaped lines are embedded in the second medium layer, the third medium layer and the fourth medium layer. The second medium layer comprises a first belt-shaped line medium upper layer, a first belt-shaped line layer and a first belt-shaped line medium lower layer which are arranged from top to bottom. The third medium layer comprises a second belt-shaped line medium upper layer, a second belt-shaped line layer and a second belt-shaped line medium lower layer which are arranged from top to bottom. The fourth medium layer comprises a third belt-shaped line medium upper layer, a third belt-shaped line layer and a third belt-shaped line medium lower layer which are arranged from top to bottom. The fifth medium layer comprises a fourth belt-shaped line medium upper layer, a fourth belt-shaped line layer and a fourth belt-shaped line medium lower layer which are arranged from top to bottom. The LTCC delay line assembly is small in size, is of a micro-strip structure in input and output and can be easily integrated with other elements.

Description

technical field [0001] The invention belongs to the technical field of microwave control circuits, and in particular relates to a delay line assembly based on Low Temperature Co-fired Ceramic (LTCC) technology. Background technique [0002] A delay line is a component or device that can delay an electrical signal for a period of time. In the design of various electronic instruments and communication systems, in order to meet the needs of certain functions, it is often necessary to use a delay line to achieve the purpose of delaying the signal for a specific period of time. In recent years, with the rapid development of the electronics industry, such components are used in precision guidance, satellite communications, and modern radar systems. [0003] Currently, commonly used delay lines include coaxial cable delay lines, bulk acoustic wave delay lines, surface acoustic wave delay lines, and fiber optic delay lines. The coaxial cable delay line was the first to enter the a...
