Introduction

The low pass filter series can be used in many communication applications such as MoCA, CATV, satellite and other systems to filter out unnecessary channels, frequencies or interference frequencies.

Soontai's low pass filters provide many features (see below).

1. Rejection better than 50dB.

2. Lowest insertion loss, signal-through-loss reduced to a minimum.

3. Excellent return loss, good impedance match reduces signal loss to keep the signal clean. (see figure)

4. Dual layer brass tubes provide the best radio frequency interference (RFI) / electromagnetic interference (EMI) protection.

We can design other models according to your specifications.

For more filter information please see the filter profile technical notes in our Tech Support.
