Claim Text:
1. A power device comprising: a transistor; a lumped element capacitance inductive capacitance analog of a transmission line configured to form an output matching circuit for the transistor, said analog of a transmission line having a first port and a second port, wherein the first port is coupled to an output of the transistor; and a directional coupler inductively coupled to said analog of a transmission line configured to form a power sensor for the transistor, wherein the power sensor comprises a third port and a fourth port; wherein an inductive element of said analog of a transmission line is formed by plurality of bonding wires, the power device further comprising a first capacitance between the first port and ground and a second capacitance between the second port and ground; wherein the directional coupler is a lumped element inductive capacitance coupler; wherein an inductive element of the directional coupler is a bonding wiring that is inductively coupled to said plurality of bonding wires, the power device further comprising a third capacitance between the third port and the second port, a fourth capacitance between the third port and ground, a fifth capacitance between the first port and the fourth port, and a sixth capacitance between the fourth port and ground; wherein the fourth port of the directional coupler is configured to provide an indication of power reflected from a load coupled to the second port.
