Product Description

Features

RFMD’s SPA2118Z is a high efficiency GaAs Heterojunction Bipolar Tran-

sistor (HBT) amplifier housed in a low-cost surface-mountable plastic

package. These HBT amplifiers are fabricated using molecular beam epi-

taxial growth technology which produces reliable and consistent perfor-

mance from wafer to wafer and lot to lot. This product is specifically

designed for use as a driver amplifier for infrastructure equipment in the

850MHz band. Its high linearity makes it an ideal choice for multi-carrier

and digital applications.
