Fiplex DVN Series are efficient duplexers, made of four or six round coaxial cavities, able to be installed in a 19“ cabinet.
These duplexers are intended to be used in high power applications, or when there is small Tx-Rx separation.
Around the pass frequencies, these duplexers display a quasi band pass response, providing an additional
selectivity that protects the receiver against interferences and reduces the noise and spurious emission of the transmitter.
Two versions are available: 4” O.D. cavities (”L” type and 7” O.D. cavities (”N” type).
Models ending in “/3” use ¾ wavelength coaxial resonators in order to improve the Q factor of the cavity.
Good thermal stability is obtained by a fine design an by the use of INVAR rods to control the tuning of  each resonator.
In order to have a long life performance, inner copper lines are silver plated and the outer aluminum conductors are alodine passivated.
Duplexers are supplied with mounting brackets for 19" racks.
Standard connectors are N female. Other connector types are available upon request.
