DPID 1800/18
Interdigital Base Station Duplexer
DESCRIPTION
The DPID 1800/18 is an 18-resonator base station duplex filter designed
to operate as a part of the combining systems on base station
installations.
The duplexer consists of two interdigital band-pass filters, which are
interconnected by a cross-over network.
The interdigital principles ensure that ripple and insertion loss figures
are kept very low over the wide port widths, and that steep slopes
immediately beside the pass ranges and heavy attenuation outside the
pass ranges are realized.
The filter is capable of operating continuously at a power level of 200 W.
The filter parts are mounted on an aluminium plate with thickness: 4
mm and dimensions: 266 x 483 mm. Total height is 36 mm. This
assembly fits nicely into a 19” rack system.
Construction and choice of materials have been carried out to ensure
that electrical characteristics are maintained over a long life-span
despite the influence of environmental factors such as corrosion,
temperature, humidity, shock and vibration.
The assembly is finished with a black, 2-component polyurethane
coating.
