Diplexers
A diplexer is a 3-port Radio Frequency (RF) filter component which is used in
multiband systems. It enables the sharing of a common antenna between two
distinct frequency bands in which each band encompasses both transmit and
receive functions. This differs from a duplexer which combines the uplink and
downlink portions of a single band.
CTS has a number of different diplexing technologies. For diplexing of widely
separated bands, in which a true low-pass filter (LPF) / high-pass filter (HPF) is
required, we have our XCBC family of cross-band combiners. The XCBC products
have low insertion loss in a small size, but with power handling up to 6W average /
60W peak power per band. For diplexing of very closely spaced bands, we have our
DPX family of diplexers which offer multiplexing of bands which are very difficult to
frequency combine.
We offer numerous challenging band combinations while sharing a universal
footprint. The DPX family supports power handling up to 3W average / 20W peak
power per band. These two families (XCBC and DPX) can flexibly be used together
to create 3-way and 4-way multiplexers. For high performance diplexers, which in
the past would have used air cavity filters, ClearPlex products can be tailored for
use in systems requiring up to 50W average / 500W peak input power where
smaller size and PCB surface mounting is desired.
