應用評估板評估IBM43RF0100 SiGe HBT晶體管在 1.9GHz CDMA驅動器應用情況;

The IBM43RF0100 Silicon-Germanium (SiGe) High
Dynamic Range, Low-Noise Transistor is a discrete
heterojunction bipolar transistor (HBT) suitable for a
wide range of RF driver applications including
spread spectrum transceivers, mobile telephones,
and portable handsets. The HBT’s high linearity and
low power consumption make it ideal for wireless
digital applications such as CDMA and TDMA.
The IBM43RF0100EV-19 Evaluation Board implements
a wideband CDMA driver amplifier at 1880
MHz and provides a convenient means to evaluate
the HBT’s performance in typical CDMA driver applications.
Performance characteristics such as gain,
SWR, P1dB compression point, adjacent channel
power, and efficiency can be analyzed and evaluated.
The evaluation board conforms to the performance
criteria listed in the following table.
