Preliminary
Product Description
Sirenza Microdevices’ SXA-289 amplifier is a high
efficiency GaAs Heterojunction Bipolar Transistor (HBT)
MMIC housed 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.
