Typical Response Curve

Installation

The DIPX 225/330 makes it possible to use only one antenna for the operation of two transceivers (one in each range). See the figure below. The antenna must be a dual-frequency antenna, e.i. it must be resonant on the actual frequencies in the two bands.

The transceivers may be used independently and will have no degrading influence on each other. Typically, the diplexer is installed next to the transceivers and only one cable is used between the diplexer and the antenna. The diplexer is suitable both for base station and mobile use.

The main tasks of the diplexer are to protect the individual receiver input from being destroyed by the transceiver in the contrary band and to ensure a lowloss path between the transceiver and the antenna which is not loaded by the other branch.
The diplexer can be operated together with any set of transceivers operating
within the 0 - 225 MHz and 330 - 1300 MHz frequency bands.

Dual-frequency antennas are available for both mobile and base station applications.
