Product information

The MPX 70/44-...-TETRA-N is an extremely small duplex crossover with 8 resonators for duplex radio systems. This compact "miniplexer" combines the requirements of a modern, space-saving and high-performance filter type.
The duplexer is available in different versions. This depends on the duplex distance, frequency, bandwidth and attenuation. The MPX 70/44-...-TETRA-N is adjustable in the range of 380-470 MHz, see also ordering information.
The MPX 70/44-...-TETRA-N models are primarily intended for Tx and Rx. operation on single frequencies (up to 90dB isolation), but can also be used with slightly reduced data for Tx and Rx operation on multiple channels, i.e. within a defined bandwidth. In this case, a factory adjustment is recommended.
The miniaturization of this crossover is achieved by using special, temperature-compensated helical resonators of high quality.
The crossover is made of extruded aluminium, the chassis is made of steel, and the semi-rigid coaxial cables and connectors are insulated with Teflon.
The crossover is coated with black vinyl to prevent corrosion.
Other models with different frequencies, duplex spacing, bandwidths and attenuations are available on request.
