A comparison of the dc and rf characteristics of single and double InP/InGaAs heterojunction bipolar transistors
Keyword(s):
The dc and rf characteristics for InP/InGaAs heterojunction bipolar transistors having a single heterojunction design were measured and compared with those for double heterojunction devices that employ a composite collector. Although the composite-collector design improves the breakdown characteristics of our devices the rf performance was not as good. This we partially attribute to the collector heterojunction, which causes "current blocking".
