摘要：
In this paper, the concept of block reuse is applied to design a dual-band power amplifier. The amplification cell is shared for each frequency band and the impedance matching networks are designed making use of switchless multiresonant circuits. The target frequencies are those of the ISM band, 433 and 915 MHz. In order to obtain a good compromise between linearity and efficiency, a class AB operation is adopted. The performance of amplifier was evaluated using post layout simulation. The results have shown 44.4 % and 44.8 % PAE peak efficiency at 29.0 dBm and 29.8 dBm output power, respectively, in the target frequencies.
