Introduction
Skyworks is a world-class supplier of high performance ceramic
band pass filters. Specializing in band pass, notch and diplexing
applications, Skyworks can cover a frequency range from 300 MHz
to 6000 MHz with surface mount or connectorized devices.
Utilizing state of the art assembly automation, Skyworks provides
cost-effective solutions meeting high performance specifications.
Skyworks’ 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.
Skyworks’ 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
Website, 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 Skyworks’ application engineering. Our application engineers
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,
Skyworks can provide the necessary support for your application
from prototype through production. In addition to the personal
attention, Skyworks 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 Skyworks’ 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, Skyworks offers aggressive
leadtimes on both prototype and volume applications.

Standard Filter Selection Guide
Skyworks has a wide range of standard filters, as well as the
capability to rapidly create new custom designs. Figure 1.1 illus-
trates our general capability for filters. If a desired requirement
falls within the listed categories, Skyworks can easily offer a suit-
able design. Beyond this general list, Skyworks has a staff of
experienced filter designers who can provide new custom and
more technologically difficult filters. In addition, the CRaFT pro-
gram functions as a useful tool when analyzing filter requirements.
Skyworks welcomes the chance to review specifications and
determine a design solution.

Design Solutions Software
CRaFT Program
Example
Designing a 915 MHz ISM band filter is a typical example of how
to use the CRaFT software. Knowing the design parameters in
advance helps to narrow down the initial design. Use the fol-
lowing procedures to complete design of this filter.
1. Use the Start button to enter the Programs menu.
2. Select Trans-Tech Design Guides and click on CRaFT.
3. Enter the desired center frequency, 915 MHz, for the filter.
4. Enter the total bandwidth, 25 MHz, necessary for the
new design.
5. Use a bandwidth definition of 1 dB.
6. For the example we are going to use a 4 mm package style
with 3 poles to the filter.
7. The D9000 material has been preselected for optimum
performance. Other material types are included for fine
tuning a design.
8. The design is now complete. The part number is listed,
TT4P3-0915P3-2530, and the design guide can easily be
printed out. In addition a typical plot has been generated to
look at attenuation where necessary.
Trans-Tech’s design software is available by visiting our website; trans-techinc.com or calling us at 301.695.9400.
9. As a final aid, there is a list of previously designed filters. If
timing is of importance, selecting one from this list removes
the time needed for prototyping a new design.
10. Sometimes a filter specification might come up with no
solution. In this case, please consult the factory for assistance
in the design.
11. After the design has been finalized, the filter can be printed.
12. Click file, choose print data sheet.
Fill out the appropriate information and fax to the number listed
on the printed quotation form. At any time, click on Help for
details and hints.
