MPX 2/6...
6-Resonator Mini-Duplexer for the 160 MHz Band
DESCRIPTION
The MPX 2/6… 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.
Model MPX 2/6 L can be tuned within the band 138-156 MHz and model
MPX 2/6 H within the band 152 - 175 MHz, both with duplex spacing
between 4 and 15 MHz.
The MPX 2/6… is primarily intended for equipment, where the TX and
RX operate on single frequencies, but it 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 with discrete-component
interconnections.
The housing is made of extruded aluminium, and the connectors are
provided with teflon insulation.
The filter is black vinyl coated to prevent corrosion.
