Product Description
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.
