Introduction
Trans-Tech Inc., a wholly-owned subsidiary of Skyworks
Solutions Inc., is a world-class supplier of high performance
ceramic band pass filters. Specializing in band pass, notch and
diplexing applications, Trans-Tech can cover a frequency range
from 300 MHz to 6000 MHz with surface mount or connectorized
devices. Utilizing state of the art assembly automation, Trans-
Tech provides cost-effective solutions meeting high performance
specifications.
Trans-Tech surface mount PCB configured filters are designed to
comply with “green” manufacturing initiatives eliminating heavy
metal elements. This configuration is designed to comply with
pending European regulations regarding the elimination of lead in
electronic assemblies. Custom assemblies can be obtained with
flat pack style SMT devices, through-hole or Sn/Pb coated PCB
surface mount designs.
Trans-Tech assembly methodology offers a wide array of designs,
from 2 mm x 2 pole – 8 mm x 10 pole band pass filters and
diplexers, to advanced band stop (notch) designs and high-pass
or low-pass filters. For typical applications and ranges of prod-
ucts, refer to the Standard Filters/Duplexers listing included in
this document. Detailed specifications, both mechanical and
electrical, are maintained for many popular designs on our
Web site, or by contacting your local sales representative.
The nature of applications utilizing a band pass filter, duplexer or
notch filter, necessitates the close interaction of the customer
and Trans-Tech application engineering. Our application engi-
neers employ the latest in simulation and circuit analysis
software with accurately defined design rules to provide rapid
turnaround on new filter designs. With our experience and
design aids, Trans-Tech can provide the necessary support for
your application from prototype through production. In addition to
the personal attention, Trans-Tech offers a computer-aided
design tool, CRaFT, to assist engineers designing filters (the latest
version can be downloaded from our Web site,
www.skyworksinc.com.
The strength of Trans-Tech designs begin with our ability to
produce our own coaxial resonators from proprietary ceramic
formulations. These resonators provide a high Q element that
allows us to maintain our low filter insertion loss values. With
numerous design package styles, Trans-Tech offers aggressive
leadtimes on both prototype and volume applications.
