Abstract: This study proposes an improved output matching design technique based on a two-stage harmonic suppression network, with the core innovation being a hybrid matching mode combining microstrip lines and lumped-parameter components in output matching. In the first-stage harmonic suppression network, a third-order Butterworth filter served as the prototype. Utilizing the Richards transformation and Kuroda rule, it is converted to a cross-shaped microstrip line, achieving high-frequency matching while suppressing second-harmonic components. The second-stage harmonic suppression network employs two series-connected LC resonant circuits to suppress the third- and fifth-harmonics. To broaden the bandwidth and enhance the circuit stability, an improved negative feedback structure based on a second-order Butterworth low-pass filter prototype was introduced. Practical circuit testing within the 0.4-1.2 GHz operating bandwidth demonstrated an output power ranging from 40.1 to 41.3 dBm and drain efficiency exceeding 51.63%, robustly validating the effectiveness of this approach.
