Abstract - Filters are key components in RF and microwave systems. At higher operating frequencies, filter design becomes increasingly difficult to implement using lumped components and the use of distributed-element filters is required. To successfully design these filters, the proper use of simulation tools is necessary. Designers must also understand and select appropriate filter technologies to meet performance goals. In order to reduce cost and take advantage of standardized processes, filter implementation on printed circuit board material can be used. A survey of the AWR Design Environment (AWRDE) is presented, including an overview of the various simulators – Microwave Office, AXIEM, Analyst – and their respective uses. Example designs of distributed filters are used to demonstrate the design flow within the AWRDE and highlight aspects of filter design while seamlessly moving between tools. An overview of distributed filters is also discussed along with design considerations for PCB materials and the corresponding fabrication processes.
