Dielectric Filter - Duplexer 
- Duplexer is a part connected to the bottom of the mobile communication terminal antenna, to separate and transfer Tx and Rx frequencies from several radio frequency signals and eliminate unwanted signals. Mono-block duplexer has been used in general.
As the duplexer occupies a large area in the mobile communication terminal, developers have been making efforts to make it very small, for which they have been researching and developing required circuits, structures and materials.
Patron’s mono-block duplexer is configured with several resonators. Its advantages include removal of the necessity of additional parts such as combination circuits for combining resonators and external circuits for patterning or holes, and realization of a moderate price for the duplexer through mass production.
Diverting from the production of mobile communication terminal parts on which we have focused on, Patron will make efforts to supply mono-block duplexers used for base stations, repeaters, DMBs and GPS.
