Abstract
A Balun assembly has a signal conductor ( ) on the balanced side of a Balun, the signal conductor ( ) being joined to a microstrip RF launch area 7 on a circuit board 6, the signal conductor ( ) having a bend of axial orientation for lower cost, reliability, avoiding contact with a ground circuit path ( ), being more suited for higher volume manufacturing, that distributes thermal expansion and contraction thereof substantially throughout to lessen stress at a junction of the signal conductor ( ) and the RF launch area ( ), and the signal conductor ( ) being of minimum length and of smooth and even curvature to lessen impedance mismatch at the junction.
