ABSTRACT
ABSTRACT
MCM has high density integration, multilayer wiring, the advantages of high
frequency performance. MCM is the important means to the miniaturization of
electronic systems. MCM is widely used in radar, communication, electronic warfare,
equipment and other military/civilian areas. Developed countries put a high value on
MCM because MCM has a lot of advantages, for example MCM raises density and
shortens interconnection space. MCM is a mainstream in the field of ic
field and microwave technology and frontier, and of great value in theoretical research
and engineering application.
Aiming at the big size of microstrip filter, this thesis adopts the filter design method
that is based on coupling matrix. The thesis calculates coupling matrix. bining
with the ic simulation software HFSS, the thesis designs six kinds of
MCM filter structure, and analyzes the general rule of filter optimization. . In this thesis,
the designed filter materials is RO4350B and the process is MCM - L. The size of
MCM filter decreases. The S11 of four cavities filter is less than -10 dB。The S11 of
hairline filter is less than -15 dB。 The S11 of open-end filter is less than -20dB。The
S11 of four cavities open loop filter is less than -15dB。
Keywords: MCM technology, microwave filter, coupling matrix, defected ground
structure, capacitive load.
