摘要
The device performance of InP/InGaAs double HBTs including DC and microwave characteristics of have been carefully investigated. The MHTs exhibit high current gain and common-emitter breakdown voltage with low junction leakages. An f(T) and an f(max) higher than 90 GHz were obtained for the devices with 1.6x5 mu m(2) emitter area. Both microwave noise and power performances for the MHBT's are comparable to the conventional InP HBTs. More important, the issues which could be important for practical device application such as device thermal resistance, 1/f noise and device stability under high temperature and high current stress were carefully investigated. The results suggest a great potential of MHBTs for microwave applications.
