Satellite-IF High Pass Filter
 
Introduction

This high pass filter series is primarily designed for use in satellite receiving systems to pass satellite-IF frequency and filter out unwanted frequencies or interference frequencies (eg, FM, TV, CATV, LTE, etc.).

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

1. High 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.

5. The power pass function allows DC power and 22 kHz control signals to pass.
    ( * This is a optional function)

We can design other models accroding to your specifications.

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

Custom filters or more details on inquires, please refer to Custom Filters.
