high-freq ckt design and lab_noteHigh-Freq Ckt Design and Lab; J-T Wu 1-1 What is High Frequency in this class? Pure circuit elements (R, L, C) are hard to realize because of parasitic elements. Elements are best thought of in terms of distributed parameters like transmission lines or line resonators. Not consider elements where modes other than the TEM (transverse electro-magnetic mode) are important. No waveguides or cavity resonators. The actual frequency limits depend upon the size of structures that can be built. Using hybrid circuits and chip transistors, it is quite possible to consider frequencies of 3……
