A novel concept for first-pass design of RF Power amplifiers for wireless communications

In this paper, a novel RF circuit design concept, namely, Partitioning Design Approach (PDA) is proposed. In comparison with the conventional RF circuit design approach, it is aimed to accomplish the complex RF circuit design tasks in a straightforward way. As a demonstrator, one class-AB RF power amplifier (PA) was designed at the centre frequency of 2.14 GHz using AlGaAs/GaAs HEMT technology. Finally, excellent agreement between the real measured RF performance and the expected simulation results has been achieved without iterative and tedious post-fabrication tuning work; the feasibility of the PDA for obtaining first-pass success in RF PA realization has been demonstrated successfully.
