Four new models cover DC to 26.5 GHz at different crossover frequencies.

Diplexers take a wideband input and divide it into two frequency bands. They also work in reverse by combining RF signals from different frequency ranges into a single output. Marki Microwave has added four models to its line, available as modules with SMA receptacles on each port. The new modules include:

Model (link to datasheet)	Low band (GHz)	High band (GHz)	Isolation (dB)
MDPX-0305	DC to 3	5 to 26.5	47
MDPX-0407	DC to 4	7 to 26.5	38
MDPX-0609	DC to 6	9 to 26.5	58
MDPX-0710	DC to 7	10 to 26.5	38

 

The modules contain microstrip filters built on a low-loss substrate. You can use them to split wideband signals or to attenuate signals in the low-frequency or high-frequency bands by terminating the unused connector with 50 Ω.
