In an embodiment, a circuit may include an input node, an output node, an internal node, a compensation circuit, and an adjustable capacitance circuit. The compensation circuit may be configured to modify a return loss of a signal received at the input node. The compensation circuit may include a first inductive element, a second inductive element, and a capacitive element. The first inductive element may couple the input node and the output node. The second inductive element may couple the output node and the internal node. The capacitive element may couple the input node and the internal node. The adjustable capacitance circuit may be configured to adjustably modify the return loss of the signal received at the input node. The capacitance circuit may be coupled to the compensation circuit.
