Popis: |
The intermodulation (IM) mechanism of HBT has been studied theoretically and experimentally. Volterra series analysis with an analytical nonlinear HBT model shows that IP3 can be greatly enhanced by using a punch-through collector structure. It is also found that the high linearity of HBT stems mainly from the almost exact cancellation between base-emitter and base-collector nonlinear current components. The fabricated HBT with a punch through collector has the IP3 of 31 dBm at a DC power consumption of 150 mW, which is 3 dB higher than those of HBTs with normal collector. |
