ABSTRACT A frequency diplexer network for ultrawideband radios focused on wireless parallel data transmission is presented. It has a combination of two bandpass filters utilizing manifold multiplexing technique. In the frequency band 6–9 GHz, two flat sub‐bands at center frequencies 6.7 and 8.3 GHz have been achieved with respect to forward transmission, input reflection, and group delay. A maximum group delay variation of 0.6 ns was measured in the sub‐bands. For low cost and simple circuit implementation, the design is implemented using the microstrip technology. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:1869–1871, 2014
