Introduction

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.

The DPX2 is available as waterproof or non-waterproof model.

Our DPX series diplexers are available in three different housings (DPX1, DPX2 and DPX3) to fit your mechanical requirements.

- Technical Notes -
 * Satellite-IF band : 950 - 2150MHz
