WIDEBAND AND NARROWBAND
Why is all this important? It is important because all RF components are classified as either narrowband (meaning narrow bandwidth) or wideband (meaning wide bandwidth). There are no hard and fast rules for the separation between narrowband and wideband, so I will make one up. If the bandwidth of a component is less than 50%, it is narrowband. If it is greater than 50%, it is wideband.
Ok, so where is all this leading? Here is the key: The wider the bandwidth of a component, the more frequencies it can accommodate, but the more it costs and the worse it performs. For instance, a narrowband passive component might have 1 dB of insertion loss (good), where an identical wideband passive component might have 3 or 4 dB of insertion ...
