Introduction
The DPX1-TV/FM diplexer can be used to combine or separate two signal bands (TV / FM band) for application in TV, FM, CATV, MMDS...etc, reception systems.
It offers many features:
1. Lowest insertion loss: TV bands through-loss < 1.0dB, reduced the insertion loss to absolute minimum.
2. Excellent return loss: Better than 16dB in essential to provide a good match of impedance so as avoid an increased in noise and to reduce signal loss to keep the signal clean.
3. High rejection: Better than 30dB provides a good isolation and avoids interference.
4. Closed cover panel and thick die-casting housing provides very good RFI shielding performance.
