MPX 70/6 H-7/9 N

6 Resonator Mini-Duplexer med N female 7-9 MHz duplex spacing

Duplex Filters MPX 70/6....

6-Resonator Mini-Duplexer for the 450 MHz band.

The MPX 70/6… is a 6-resonator miniaturized duplex filter for duplex radiotelephones. This compact "miniplexer” meets the demand for a modern, space saving, high performance filter type.

The duplexer is delivered in a low band version: MPX 70/6 L, tunable within the 406 - 440 MHz range, and a high band version: MPX 70/6 H, which is tunable within the 430 - 470 MHz range. These models are again delivered in 4 different versions according to required duplex spacing. 

The MPX 70/6… models are primarily intended for equipment, where the TX and RX operate on single frequencies, but they can also, however with slightly reduced data, be used where the TX and RX operate on several channels, i.e. within a certain port bandwidth. In the last case, factory tuning is recommended.

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.

MPX 70/6... is coated with black vinyl to prevent corrosion.
