Introduction

This low 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, high-band satellite signals, WiFi, 802.11, Bluetooth, etc.).

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 accroding to your specifications.

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