Low PIM 380MHz-386.5MHz/390MHz-396.5MHz UHF Cavity Combiner With DIN-Female Connector

The CUD00380M03965M65D from Concept Microwave is a Cavity Combiner with passbands from 380-386.5MHz and 390-396.5MHz with Low PIM ≤-155dBc@2*43dBm. It has an insertion loss of less than 1.7dB and an isolation of more than 65dB. It is available in a module that measures 265mm x 150mm x 61mm. This RF cavity combiner design is built with DIN connectors that are female gender. Other configuration, such as different passband and different connector are available under different model numbers.

Low PIM stands for “Low passive intermodulation.” It represents the intermodulation products generated when two or more signals transit through a passive device with nonlinear properties. Passive intermodulation is a significant issue within the cellular industry and it is extremely difficult to troubleshoot. In cell communication systems, PIM can create interference and will reduce receiver sensitivity or may even inhibit communication completely. This interference can affect the cell that created it, as well as other nearby receivers.
