Abstract
A bidirectional matching network is disclosed. In an exemplary embodiment, an apparatus includes a first matching circuit connected in a first signal path between a node and a first amplifier, the first matching circuit configured to translate an off-state impedance of the first amplifier to a first translated off-state impedance. The apparatus also includes a second matching circuit connected in a second signal path between the node and a second amplifier. The second matching circuit configured to translate an off-state impedance of the second amplifier to a second translated off-state impedance. The second translated off-state impedance is configured to reduce power loss associated with a first signal flowing in the first signal path and the first translated off-state impedance is configured to reduce power loss associated with a second signal flowing in the second signal path.
