DPF 2/6...
6-Cavity Duplexer for the 160 MHz Band
DESCRIPTION
The 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 coated with black vinyl to prevent corrosion.

ORDERING INFORMATION
When ordering, please use the table above to select the appropriate
ordering designation for the desired filter type. If duplex TX and RX
frequencies are stated when ordering, the duplexers are delivered factory
adjusted. If TX and RX frequencies are not stated, the filters are delivered
non-adjusted.
Special configurations of this filter type may be quoted on request. For
instance, the filter can be delivered with other connector types or with flying
leads (RG 316 coaxial cable) terminated with connectors or for soldering-
connection.
