Abstract
Power amplifiers including balanced coaxial baluns are described. One example includes first and second amplifiers coupled to a balanced pair of first and second microstrip lines on a circuit board. A balun is coupled between the microstrip lines at a balanced end and between a conductive trace and a ground plane of the circuit board at an unbalanced end of the balun. The balun includes a coaxial balun line and a surface mount balancing inductor. The coaxial line includes center and shield conductors. A first end of the center conductor is coupled to the first microstrip line and a first end of the shield conductor is coupled to the second microstrip line at the balanced end of the balun. The balancing inductor is coupled between the first microstrip line and the ground plane to maintain symmetry for the balanced pair of microstrip lines.
