A "Pass Band" filter passes one band of frequencies. The graph you posted shows the features of all such filters. No response at low frequencies - an ideally flat response over its pass band - no response at higher frequencies. That is what "Pass Band Filter" means. It can be regarded as a high pass and a low pass filter, combined. They can be made with design which uses just Rs and Cs. See this link and then google using the terms in the title of your OP.
