DPF 2/6-SHT-...
6-Cavity Duplexer for the 175 - 250 MHz Band
DESCRIPTION
The DPF 2/6-SHT-… is a 6-cavity duplex filter for duplex
radiotelephones.
This duplexer is delivered in a low band version type
DPF 2/6-SHT- L, tunable within 175 - 250 MHz, medium band version
type DPF 2/6-SHT-M, tunable within 200 - 230 MHz and a high band
version type DPF 2/6-SHT-H, tunable within 230 - 260 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-SHT-… 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.

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.
PLEASE NOTE
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.
