DPX1 Series
TV / FM Diplexer

* CE Approved

* Low Insertion Loss

* High Rejection

* Excellent Return Loss

* Waterproof (alternative)

* Suitable for
   TV/FM/CATV/MMDS Systems

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.


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

2. Excellent return loss: Better than 16dB is essential to provide a good impedance match so as
    avoid increased noise and to reduce signal loss to keep the signal clean.

3. High rejection: Better than 30dB provides a good isolation and avoids interference.
