Abstract
A hybrid low voltage distributed power amplifier structure ( ) provides improved efficiency by forming drain transmission line inductors ( ) on a substrate ( ) while the rest of the amplifier is built in IC form ( ). A wirebond interconnection ( ) is made between the IC's drainline capacitors ( ) and the substrate's drainline inductors ( ) which are a higher impedance point in the circuit. As a result, the wirebond inductance becomes negligible and has little or no impact on the power amplifier's performance.
