in low-cost surface-mountable plastic package. These HBT
MMICs are fabricated using molecular beam epitaxial growth
technology which produces reliable and consistent
performance from wafer to wafer and lot to lot.
These amplifiers are specially designed for use as driver
devices for infrastructure equipment in the 5-2000 MHz cellular,
ISM, WLL and narrowband PCS applications.
Its high linearity makes it an ideal choice for multi-carrier as
well as digital applications.
