Description

A kind of matrix device using point power splitters such as microstrip line

Technical field

This utility model relates to a kind of matrix device, particularly to a kind of matrix device using point power splitters such as microstrip line.

Background technology

Power splitter is a nucleus module circuit in matrix device, the excellent systematic function the most directly determining whole matrix device of power splitter performance, power splitter design is broadly divided into lumped parameter power divider and the big class of distributed constant power divider two, wherein distributed constant power divider refers to microstrip power divider, design matrix equipment, conventional method great majority all have employed the method for designing of lumped parameter.The shortcoming of lump type power divider circuit is, its processing technology is more complicated, and part debugging efforts needs artificial multiple welding to complete, and quality is difficult to ensure；The too much precision depending on the components such as used inductance, electric capacity, resistance, the precision comparison difficulty of component improves, thus affects the concordance of whole circuit, and matrix device is often at line, for the ease of carrying, miniaturization to be paid the utmost attention to.

Microstrip line is to print very thin one layer on circuit boards, generally thickness is at 0.1mm once, no matter will be better than the lump type power divider circuit of routine on volume or in quality, it is highly developed that present printing technology has developed, in microstrip circuit, as long as ensureing accurate printing technology, extraordinary effect just can be reached.Microstrip circuit uses the components such as inductance, electric capacity, resistance simultaneously hardly, so circuit concordance is the best.
