ABSTRACT:
An unbalanced to balanced antenna matching unit (AMU) is capable of operating over a relatively large frequency range by utilizing multiple transformers connected in series, with a set of bypass switches used to control the number of transformers that are "active" in the matching unit at any particular time. Complex impedance matching by the AMU is controlled by a variable capacitor in parallel with the multiple transformers and a variable capacitor in series with the unbalanced input. The parallel variable capacitor may be located on either side of the transformer arrangement. The transformer output may be configured to switch between matching either a low impedance antenna or a high impedance antenna.
