Introduction

The DPX1 VHF/UHF diplexer can be used to combine or separate two signal bands (VHF / UHF band) for application in TV, CATV, MMDS...ect. reception systems.

If a poor quality diplexer is used, signal quality is affected and interference occures.

The DPX1 series is a high performance diplexer that offers many features.

1. Lowest insertion loss: VHF/UHF band-through-loss <1.0dB. Signal-through-loss reduced to
    an absolute minimum.

2. Excellent return loss: Better than 18dB is essential to provide a good impedance match so as
    to avoid increased noise and to reduce signal loss to keep the signal clean.

3. High rejection: Better than 45dB provides a good isolation and avoids interference.

The electrical curve is shown in fig. 1, 2, specifications in table 2.
