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.
