Modeling A Printed VHF Balun Leveraging EM Simulation Techniques
2014-04-03 12:49:54| rfglobalnet Downloads
The use of printed microstrip couplers in power amplifiers operating at microwave frequencies above 1GHz has been well established and numerous papers have been written about the design of such structures. It is surprising, however, that little has been written about the subject of printed baluns (BALanced to UNbalanced)— electrical devices that convert between a balanced signal and an unbalanced signal. Even more surprising is that the dominant approach to power combining at VHF and UHF is via coaxial cables, which comes with inherent assembly, cost, and thermal issues.
