Introduction

Band pass filters are used in many communication applications such as MoCA, CATV and satellite reception to isolate a desired band.

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

1. Rejection better than 50dB. (see figure)

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 copper tubes provide the best radio frequency interference (RFI) / electromagnetic interference (EMI) protection.

We can design other models according to your specifications.

For more filter infomation please see the filter profile technical notes in our Tech Support.
Custom filters or more details on inquires, please refer to Custom Filters.
