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.
