RF2173 Theory of Operation and Application Information The RF2173 is a three-stage device with 32 dB gain at full power. Therefore, the drive required to fully saturate the output is +3dBm. Based upon HBT (Heterojunction Bipolar Transistor) technology, the part requires only a single positive 3V supply to operate to full specification.2.4 Heterojunction Bipolar Transistors The idea behind the heterojunction bipolar transistor (HBT) is as old as the transistor itself. It was proposed by W. Shockley in 1948 and subsequently patented by him in 1951  . A bipolar transistor consists of two PN junctions positioned head-to-tail sharing a common region that is the base. The juxtaposition of these two junctions leads to an NPN or PNP junction transistor in which the two types of carriers intervene. A representation of a bipolar transistor is shown in Figure 8.19 below.

The heterojunction bipolar transistor (HBT) is an improvement of the BJT that can handle signals of very high frequencies up to several hundred GHz. It is common in modern ultrafast circuits, mostly RF systems. 10RF Device DataFreescale SemiconductorMMG3014NT150 OHM TYPICAL CHARACTERISTICSTable 12.
