Bandpass Filtering Power Amplifier With Wide Stopband and High Out-of-Band Rejection

In this brief, a power amplifier (PA) with excellent integrated filtering characteristics is presented. The designed process is based on a novel impedance transformer (IT) consisting of cascaded coupled-line sections with stubs. The proposed IT generates four transmission zeros (TZs), which not only...
