Separate
Duplexer / Filter
This type of dielectric ceramic filter is formed with
multiple coaxial resonators, and a coupling block as shown
in the diagrams below. |
 |
| 2 or more tube-like coaxial
resonators in different sizes (2mm to 10 mm in diameter)
are combined and a coupling block which looks like a square
plate is connected to each resonator with a coupling pin
inserted into the center hole of each coaxial resonator.

|
Monoblock Duplexer / Filter
Unlike the above mentioned Separate type
filter, the Monoblock type filter is a single ceramic block
with multiple holes passing through the ceramic block.
