The FH Series from LARK Engineering are bandpass filters that operate from 5 to 30 GHz with a bandwidth of 2% to 5%. These bandpass filters can be customized to have 3 to 5 sections and a return loss of more than 10 dB. Insertion loss depends on the number of sections, configuration, and type of substrate used. The filters are available in a surface mount package and can be easily interconnected with other printed circuit boards such as Micro-strip, CPW, Strip line, etc. They are ideal for 5G next generation wireless networks.
