AlGaAs/InGaAs HBTs with selectively-regrown extrinsic base regions have been developed. This HBT structure successfully decreases base resistances by 1/4, compared to the conventional HBT structures Maximum oscillation frequency of the HBT is 280 GHz. The newly developed HBTs have opened up applications in millimeter wave ranges. A 26-GHz 3.6-W power amplifier and a DC-60 GHz ultra broad band amplifier were developed by using this new technology.
