Popis: |
This paper describes the optimization of Silicon Germanium (SiGe) NPN bipolar transistors for power amplifier performance. Minimizing the collector resistance and barrier effects in a power device are important to optimize the RF characteristics. Overall, we demonstrate that by optimizing the Ge retrograde design, one can improve the large signal performance to provide 66.5% Power-Added-Efficiency (PAE) at an output power of 15.4dBm, with 14.1 dB of peak Gain (G p ) and 14.1 dBm P1dB, without degrading BV ceo . |
