The key active device is a SHBT
, characterized by ft = 150 GHz, fmax = 150 GHz (at Ic = 1 mA/[micro]m) and BVCEO in excess of 4.5 V.

Based on inherent performance only, it is believed that InP HBT (SHBT
and DHBT) will be the dominant technology for affordable high speed OEIC applications.
Figure 11 shows the reverse recovery characteristics of a conventional single HBT (SHBT
) and those of the new DHBTs with sinusoidal excitation.
