Introduction

This band pass filter series is designed for use in satellite reception systems(950-2150MHz) to pass only satellite signals and filter out unnecessary frequencies or interference frequencies
(e.g. FM, TV, CATV, WLAN, 802.11, Bluetooth, etc.).

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

1. Rejection better than 45dB. (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 accroding 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.
