Technical trends in filters for

These days we can see more and more applications being installed in communication

devices, W-LAN in notebook PCs, Bluetooth and digital terrestrial broadcasting

applications in cellular phones.

In the future, wireless communication and broadcasting technologies will continue

to further develop, and the wireless market which supports them , including wireless

components, will further expand as well.

In this ubiquitously connected society, ICs used in communication systems, and wireless

devices are required to be high-performance, smaller, and inexpensive.

In this article, we will explain ﬁlter processes, Taiyo Yuden's ﬁlter lineup, and notiﬁcation

for using ﬁlters in desigs in such wireless devices.

The materials of multilayer ﬁlters

Multilayer ceramics ﬁlters, which are used for

frequency bands ranging from several hundreds

MHz to several GHz, are composed of low-resist-

ance conductor materials, such as Ag and Cu, and

dielectric materials. The conductor materials are

mainly composed from Ag-based materials.

This dielectric material contains an Ag con-

ductor, so we use low temperature co-ﬁred

ceramic(LTCC) materials, which can be baked
