Preliminary
Product Description
Sirenza Microdevices鈥?SXA-3318B amplifier is a high
efficiency GaAs Heterojunction Bipolar Transistor (HBT)
MMIC housed in a 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 400-2500 MHz
cellular, ISM, WLL, PCS, W-CDMA applications.
Its high linearity makes it an ideal choice for multi-carrier as
well as digital applications.
