heterojunction bipolar transistor

[¦hed·ə·rə‚jəŋk·shən ′bī‚pōl·ər tran‚zis·tər]
(electronics)
A bipolar transistor that has two or more materials making up the emitter, base, and collector regions, giving it a much higher maximum frequency than a silicon bipolar transistor. Abbreviated HBT.

The semiconductor technologies used for RF power amplifiers in today's wireless telephones have not solidified into a single definitive solution due to the many factors a designer is forced to trade off to simultaneously meet cost, size, performance, modulation scheme and time-to-market requirements now measured in months, Regardless of the semiconductor device technologies used (MESFET, pseudomorphic high electron mobility transistor, GaAs heterojunction bipolar transistor (HBT), SiGe HBT or Si BJT), amplifier designs must be cost effective and compact, offer competitive performance and be simple to implement.
