[AN]Agilent_AN154_S-Parameter DesignAgilent AN 154 S-Parameter Design Application Note Introduction The need for new high-frequency, solid-state circuit design techniques has been recognized both by microwave engineers and circuit designers. These engineers are being asked to design solid state circuits that will operate at higher and higher frequencies. The development of microwave transistors and Agilent Technologies’ network analysis instrumentation systems that permit complete network characterization in the microwave frequency range have greatly assisted these engineers in their work. The Agilent Microwave Division’s lab staff has developed a high frequency circuit design seminar to assist their counterparts in R&D labs throughout the world. This seminar has been presented in a number of locations in the United States……
