摘要： A matching network and method for matching a source impedance to a load impedance is provided. A bias feed microstrip structure is coupled to a direct current (DC) voltage source and has a bias feed microstrip electrical length less than one fifth of a fundamental wavelength of a fundamental frequency component of an input signal. A harmonic impedance transformation network can be configured to compensate for parasitic reactances of a precursor element. A tuned impedance element presents a short circuit impedance at the second harmonic impedance transformation network terminal for harmonic frequency components and presents a higher impedance for the fundamental frequency component. A fundamental impedance transformation network is configured to match a fundamental impedance transformation network input impedance for the fundamental frequency component to a load impedance of a load. Multiple instances of the harmonic impedance transformation network and the tuned impedance element can be provided.
