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 formation and is RoHS compliant per EU Directive 2002/95. This
Optimum Technology package is also manufactured with green molding compounds
Matching® Applied
that contain no antimony trioxide or halogenated fire retardants.

Description
VC1 is the supply voltage for the first stage transistor. The configuration as shown on the Application Schematic is
required for optimum RF performance.
VBias is the bias control pin for the active bias network. Recommended configuration is shown in the Application Schematic.
RF input pin. This pin requires the use of an external DC blocking capacitor as shown in the Application Schematic.
VPC2 is the bias control pin for the active bias network for the second stage. The recommended configuration is shown in
the Application Schematic.
RF output and bias pins. Bias should be supplied to this pin through an external RF choke. Because DC biasing is present
on this pin, a DC blocking capacitor should be used in most applications (see Application Schematic). The supply side of
the bias network should be well bypassed. An output matching network is necessary for optimum performance.
Exposed area on the bottom side of the package needs to be soldered to the ground plane of the board for thermal and
RF performance. Several vias should be located under the EPAD as shown in the recommended land pattern.
