De-Multiplexer for Broadcast and Navigation Signals

FDMX2 is a compact table top unit for the selective splitting of a frequency multiplex signal into the different broadcast bands and to the L1 satellite navigation band. For the simulation of active antennas each output has an internal DC load. The presence of phantom voltages is indicated via LEDs on the device. 

Dual AM/FM/DAB, DAB, DVB-T, GNSS, SDARS internal DC loads


Splitting in Broadcast and GNSS

FDMX2 has coded Fakra connectors for the direct connection to the antenna inputs of the devices under test (DUT). As output signals the broadcast bands AM/FM, DAB, DVB-T und SDARS and the GNSS L1 band for satellite navigation (GPS, Galileo, GLONASS, Beidou) are selective available. The broadcast bands AM, FM and DAB are dual available at a combined Fakra connector. Additional the DAB signal is let out at separate Fakra connector. A RF cable set for the connection of the FDMX2 to the antenna ports of the DUT is part of delivery.

Internal DC Loads

For the simulation of active antennas FDMX2 has six DC loads. The presence of phantom voltages is indicated via LEDs on the device.

High Quality, Compact Design

FDMX2 has a rugged shielded metal housing and is suitable as table top unit.


FDMX2 is used in combination with the multicouplers of the WSDU series. It is used in signal distributions for the test of multimedia systems for automotive, in research and development( R&D) and in production.
