Ultraminiature LC Filters

Source: Trilithic Inc.

Many filter applications can be satisfied by a low ripple Chebyshev design. This type of filter combines low VSWR in the passband, excellent selectivity, and good ultimate attenuation in the stopbands.

Special filter realizations such as Butterworth, Bessel, Linear Phase, Gaussian, and Elliptic responses may be used to solve unique problems. In addition, the LC filter topology can be customized to satisfy your requirements, such as additional rejection on the low frequency side of the passband or arithmetically symmetric rejections around the passband.

Below you will find a few examples of our design capabilities.

These examples by no means limit our capability.
