A wide bandpass filtering power amplifier using discriminating coupling is disclosed, which comprises a DC bias circuit, an input impedance matching circuit, a transistor and an output impedance matching circuit. The DC bias circuit is connected to the input impedance matching circuit which is further connected to the transistor, and the transistor is further connected to the output impedance matching circuit which comprises a tuning microstrip line and a bandpass filter. The complexity and the area of the impedance matching circuit in the power amplifier are effectively reduced. At the same time, the filtering PA has good frequency selectivity by using the discriminating coupling BPF. Meanwhile the work efficiency and bandwidth of the filtering power amplifier are effectively improved by taking both of the extended continuous mode theory and filter synthesis theory into account.
