Procom MPX 70/44-...-TETRA-N

The MPX 70/44-...-TETRA-N is a 8-resonator miniaturized duplex filter for duplex radiotelephones. This compact “miniplexer” meets the demand for a modern, space saving, high performance filter type.
The MPX 70/44-...-TETRA-N models are primarily intended for equipment, where the TX and RX operate on several channels, i.e. within a certain port bandwidth, but it can also be used where the TX and RX operate on single frequencies with even better performance on insertion loss and attenuation (up to 90 dB).
The duplexer is available in a variety of different versions depending on duplex spacing, frequency, bandwidth and attenuation.
 The MPX 70/44-...-TETRA-N is tunable within 380 - 470 MHz range.
 See also “Ordering information”.
The miniaturization of the filter has been realized by using special high-Q, temperature compensated helical resonators.
The housing is made of extruded aluminium, the chassis of steel, and teflon insulation has been applied in the rigid coaxial cables and in the connectors.
The filter is black vinyl coated to prevent corrosion.
Other models with different frequencies, duplex spacing, bandwidth and attenuation are available on request.
