A novel balanced power amplifier (BPA) using compact coupler with rhombus resonators is presented. In this design, a new method is presented to analyze the proposed rhombus‐shaped resonator based on the LC equivalent circuit. A new class F power amplifier is designed to improve performances of the B...
