BALUN Basic Information The word “balun” is a portmanteau term formed from the words “balanced” and “unbalanced” in which “balanced” implies a differential configuration and “un-balanced” represents a single-ended configuration. As shown in Figure1 , a balun is a transformation block between a ...
WebThe balun has a long and illustrious history, first documented in the literature as a device to feed the television transmitting antenna for the Empire State Building1 in 1939. Since then designs have evolved dramatically, and applications have evolved beyond driving differential antennas to include balanced mixers, amplifiers, and signaling lines of all types. Webof differential signals. The requirements of the on-chip transformer baluns for LNA and PA are quite demanding. For practical purposes, the on-chip transformer balun must be small and compatible with the size of other on-chip inductors. For an LNA, the balun needs to provide 0-7803-7694-3/03/$17.00 B 2003 IEEE

WebIn an ideal balun, signals appearing at the output of balanced ports are of equal amplitude and differ in phase by 180º. In reality, even in a well designed balun/transformer, there is a small amplitude and phase unbalance. Amplitude unbalance is difference in amplitude (in dB) and phase unbalance is deviation from 180º phase, in degrees. phil mendysWeb07. feb 2008. · The conditions are investigated under which standard digital bulk Si technology can yield efficient on-chip antennas and baluns for fully differential … phil mendelson facebookWeb2. The answer will largely depend on the internal makeup of the input port of the microcontroller. A DC path to ground from the balanced RF input port is likely to be undesirable, especially if the manufacturer has suggested capacitive coupling.
