Wideband power amplifiers with harmonic traps

An electronic circuit comprising:

• an amplifier having an output node;
• and
• an output impedance matching network comprising:
• an input electrically connected to the output node of the amplifier,
• one or more harmonic traps electrically connected to the input,
• a shunt-L path electrically connected to the input,
• a baseband termination path electrically connected to a RF cold point node of the shunt-L path,
• an inductance electrically connected between the input and an output of the output impedance matching network;
• and
• a bias transmission line that electrically connects the output to a voltage source, wherein the bias transmission line has an adjustable electrical length.

An output impedance matching network of an amplifier, the output impedance matching network comprising:

• an input electrically connected to an output node of the amplifier;
• one or more harmonic traps electrically connected to the input;
• an inductance electrically connected to the input;
• a capacitor electrically connected in series with the inductance between the inductance and a ground node;
• a baseband termination path coupled between the ground node and a node coupled between the inductance and the capacitor;
• an output coupled to a load, wherein the output impedance matching network is an impedance inverter that provides a 90 degree insertion phase between the input and the load;
• an additional inductance electrically connected between the input and the output of the output impedance matching network;
• and
• a bias transmission line that electrically connects the output to a voltage source, wherein the bias transmission line has an adjustable electrical length.
