A High‐Efficiency Concurrent‐Capability Tri‐Band Power Amplifier Based on T‐ and L‐Section Dual‐Band Transformers

ABSTRACT This paper presents a simple three‐frequency matching structure formed by cascading T‐ and L‐Section dual‐band transformers (DBT). The main principle is that the T‐ and L‐Section DBT achieves tri‐band operate by jointly matching at three target frequencies, and based on...
