Abstract:
Embodiments of RF amplifiers and packaged RF amplifier devices each include a transistor with a drain-source capacitance that is relatively low, an input impedance matching circuit, and an input-side harmonic termination circuit. The input impedance matching circuit includes a harmonic termination circuit, which in turn includes a first inductance (a first plurality of bondwires) and a first capacitance coupled in series between the transistor output and a ground reference node. The input impedance matching circuit also includes a second inductance (a second plurality of bondwires), a third inductance (a third plurality of bondwires), and a second capacitance coupled in a T-match configuration between the input lead and the transistor input. The first and second capacitances may be metal-insulator-metal capacitors in an integrated passive device.

Claim (Index 25):
The method of  claim 24 , further comprising:\n coupling a second integrated passive device to the device substrate between the transistor die and the output lead, wherein the second integrated passive device includes a third capacitance and a fourth capacitance, wherein the third capacitance includes one or more third capacitors that are integrally formed with the second integrated passive device, and the fourth capacitance also is integrally formed with the second integrated passive device; creating an output-side harmonic termination circuit by connecting a fourth inductive element in the form of a fourth plurality of bondwires between the transistor output terminal and the third capacitance, wherein an equivalent capacitance from a combination of the fourth inductive element and the third capacitance in series effectively increases the drain-source capacitance by at least 10 percent, and the output-side harmonic termination circuit resonates at a harmonic frequency of the fundamental frequency of operation of the RF amplifier device; and creating a portion of an output-side impedance matching circuit by connecting a fifth inductive element in the form of a fifth plurality of bondwires between the transistor output terminal and the fourth capacitance, wherein the fifth plurality of bondwires and the fourth capacitance are directly connected.
