DOWNLOAD EBOOKIn microwave network analysis, proper matching of the measurement system is necessary to prevent measurement errors and provide a proper terminating impedance for the device-under-test. To obtain this matching, a buffer amplifier is often used in the first stage of the network analyzer. This study describes the design and analysis of one such amplifier for use in a future generation of Hewlett-Packard network analyzers. Design goals, specifically for return loss, were set. The amplifier was to operate in the 100 kHz to 3 GHz range. A common base amplifier was chosen, and an analysis performed to determine problem areas. Methods of correcting the problem areas were presented, and a breadboard was constructed for measurement purposes. The measurements presented indicate that the final circuit met all specifications.
