6-Cavity Duplexer for the 160 MHz Band
The PROCOM DPF 70/6...is a 6-cavity duplex filter for duplex radiotelephones.The DPF 70/6… can be adjusted within the complete 406 - 470 MHz band. The duplexer can be delivered in four different versions according to required duplex spacing. See also “Ordering information“ below. The DPF 70/6... 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 filter uses full-length 1/4 cavities in a compact, extruded aluminium housing. The chassis is made of passivated steel, and teflon insulation has been applied in the coaxial cables and in the connectors. The filter is black vinyl coated to prevent corrosion.
Suggested replacement for: Tait: model number: T993-050-06-00, T993-050-06-01. Motorola HFE8400A, TDE7780A (Fits inside a Motorola or Tait repeater-housing)

6-Cavity Duplexer for the 160 MHz Band
The PROCOM DPF 2/6... is a 6-cavity duplex filter for duplex radiotelephones.This duplexer is delivered in a low band version type DPF 2/6 L, tunable within 138 - 156 MHz and a high band version type DPF 2/6 H, tunable within 152 - 175 MHz. These models are again delivered in 3 submodels, each dedicated to work with a certain duplex spacing. See “Ordering information“ below. The DPF 2/6… 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 filter has very small physical dimensions owing to the use of high-Q, temperature compensated helical resonators. The housing is made of extruded aluminium, the chassis of passivated 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.
Suggested replacement for: Tait model numbers: T993-050-02-01, T993-050-05-01.
Motorola model numbers: HFD8188A, HFD8189A, HFD8190A
(Fits inside a Motorola or Tait repeater-housing)

 

High-power Interdigital Base Station Duplexer
The PROCOM 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 483mm. 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.

High-power 6-Resonator Helical Duplex Filter
The PROCOM 2/6-HX-150 (185x250x50mm) high-power low-loss Duplexer uses high Q helical resonators in a compact, extruded aluminium housing. The chassis is made of passivated steel, teflon insulation has been applied in the coaxial cables and in the connectors. The filter is black vinyl coated to prevent corrosion. The standard connector is N. For use with a 1.2 MHz to 3 MHz TX/RX split. Available in frequencies from 30 MHz to 180 MHz in different models (Kindly specify frequencies when ordering.)

High Power Duplex Filter for the 150 MHz Band
The POCOM DPF 2/33-250 is a high power base station duplex filter for the 140 - 175 MHz range. The use of large ø250 mm cavities means a high Q, resulting in a very narrow duplex spacing (250 kHz.) The large dimensions also means a high power rating. Unloaded Q of a single cavity is approx. 8000. High frequency stability on temperature and power. Mounted on 19“ brackets.

6-Resonator Mini-Duplexer for the 450 MHz Band
The PROCOM 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. The filter is black vinyl coated to prevent corrosion.
