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 |
