Band Pass Filters

Trans-Tech 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 250 MHz to 7000 MHz with surface mount or connectorized devices. Utilizing state-of-the-art assembly automation, Trans-Tech provides cost-effective solutions meeting high performance specifications.

Tran-Tech's 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's assembly methodology offers a wide array of designs, from 2 mm x 2 pole - 20 mm x 10 pole band-pass filters and Diplexers, to advanced band stop (notch) designs and high-pass or low-pass filters. Typical applications and ranges of products are listed in our product documentation. 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, duplexor or notch filter, necessitates the close interaction of the customer and Trans-Tech 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, Trans-Tech can provide the necessary support for your application from prototype through production.

The strength of Trans-Tech's 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.
