Abstract
Power amplifier electronics for controlling application of radio frequency (RF) energy generated using solid state electronic components may further be configured to control application of RF energy in cycles between high and low powers. The power amplifier electronics may include a semiconductor die on which one or more RF power transistors are fabricated, an output matching network configured to provide impedance matching between the semiconductor die and external components operably coupled to an output tab, and bonding ribbon bonded at terminal ends thereof to operably couple the one or more RF power transistors of the semiconductor die to the output matching network. The bonding ribbon may have a width of greater than about five times a thickness of the bonding ribbon.
