Design of Power Amplifier for Multi-mode Multi-standard Front-end based on BiCMOS technology

The class-E amplifier adopts 0.13μm SiGe BiCMOS technology, covering the most communication standards within 1.75G-2.75G and meets the varieties of communication standards of communication equipment. The design also uses lossy matching, matching compensation technology to enhance the overall performance of the amplifier. The post-simulation results show that the power amplifier is unconditionally stable in the working band of 1.75G-2.75G, the power amplifier is unconditionally stable, the circuit stability coefficient is greater than 22, the Sll is less than -15dB in the frequency band, shows that the input matching performance is good. The output power is more than 26dBm, the power gain is more than 21dB, the PAE is more than 50%, and the peak efficiency reaches 60%.
