A multi-band combiner handles and combines signals across multiple frequency bands, allowing for the integration of different frequency ranges into a single output. This is essential for systems that need to manage several distinct bands simultaneously, such as in modern wireless networks with diverse frequency allocations.
In contrast, a same-band combiner specifically combines signals within a single frequency band. It focuses on aggregating multiple signals operating on the same frequency, which helps in optimizing resource usage and managing interference within that particular band.
Essentially, the key difference is that a multi-band combiner deals with multiple frequency ranges, while a same-band combiner is limited to one frequency band.
