Satellite-IF / TV Diplexers
DPX2 series


* Mini Size

* Wideband, up to 2.3 GHz

* Flat Passband

* Low Insertion Loss

* Rejection 40dB

* Excellent Return Loss

* High Stability

* Die-casting Housing

* High RFI Shielding

* Precision Connector Thread

* Good Plating Quality

* Good Weather Resistance

The DPX2 is a mini-size diplexer series. Despite its small size it has exceptional performance such as a typical rejection of 40dB, a return loss of 14dB (typ.), a very even pass band and an insertion loss of less than 1dB (typ.).

The DPX2 offers high performance over the whole frequency spectrum, up to 2300MHz. Insertion loss is less than 1dB and return loss 14dB (typ.). This makes the DPX2 an ideal choice for digital satellite systems.

In addition to the general models in the table below, the TV/ CATV and satellite-IF bands can be designed according to customer specifications.

For more diplexer products, please see our diplexer category.



1. Use diplexers for system set-up.




2. Use diplexers for 4-way system set-up.


* The direction of diplexer function ports
   depends on actual diplexer.
