| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper presents a low 1/f noise and high reliability InP/GaAsSb DHBT developed for automotive radars. To improve 1/f noise and reliability, experimental analyses on the recombination current have been carried out. As a result, we have clarified that the recombination current which can affect 1/f noise and reliability, originates from the surface of the base. We have optimized the base surface structure with the ledge and SiN passivation film. The optimized DHBT offers the lower 1/f noise level than that of the non-optimized DHBT by 7 dB. Additionally, in the high temperature burn-in test, no degradation has been observed even after 1,000 hrs. The W-band oscillator with the optimized HBT delivers the lower phase noise of -107 dBc/Hz at 1MHz-offset compared with that of the non-optimized HBT oscillator by 10 dB. | |
