Abstract :
Large signal measurements of an active transistor based balun using an Large Signal Netork Analyzer (LSNA) have been performed to study the phase and amplitude imbalance as a function of input power and frequency. The LSNA measurements are compared and verified against small signal parameters from a standard Vector Network Analyzer (VNA). It is shown that LSNA measurements can give further information of the nonlinear behavior of active baluns.
