Product Description
Features
RFMD’s SGA8543Z is a high performance Silicon Germanium Heterostructure Bipo-
lar Transistor (SiGe HBT) designed for operation from 50MHzto3.5GHz. The
SGA8543Z is optimized for 3.3V operation but can be biased at 2.7V for low-volt-
age battery operated systems. The device provides low NF and excellent linearity at
a low cost. It can be operated over a wide range of currents depending on the
power and linearity requirements.The matte tin finish on the lead-free “Z” package
is applied using a post annealing process to mitigate tin whisker formation and is
RoHS compliant per EU Directive 2002/95. The package body is manufactured
with green molding compounds that contain no antimony triox-
