Product Description
Features
RFMD’s SPA2318Z is a high efficiency GaAs Heterojunction Bipolar Transistor (HBT)
amplifier housed in a low-cost surface-mountable plastic package. These HBT
amplifiers are fabricated using molecular beam epitaxial growth technology which
produces reliable and consistent performance from wafer to wafer and lot to lot.
This product is specifically designed for use as a driver amplifier for infrastructure
equipment in the 1960MHz and 2140MHz bands. Its high linearity makes it an
ideal choice for multi-carrier and digital applications. The matte tin finish on the
lead-free package utilizes a post annealing process to mitigate tin whisker forma-
tion and is RoHS compliant per EU Directive 2002/95. This
