FREQUENCY DIPLEXER NETWORK FOR WIRELESS PARALLEL DATA TRANSMISSION AND ULTRAWIDEBAND SYSTEMS UTILIZING MANIFOLD TECHNIQUE

摘要

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.
