Bipolar Transistor (HBT) MMIC housed in low-cost surface mountable plas-
tic package. These HBT MMICs are fabricated using molecular beam epi-
taxial growth technology which produces reliable and consistent
performance from wafer to wafer and lot to lot. These amplifiers are spe-
cially designed for use as driver devices for infrastructure equipment in
the 400 MHz to 2500 MHz cellular, ISM, WLL, PCS, WCDMA applications.
Its high linearity makes it an ideal choice for multi-carrier as well as digital
