Stanford Microdevices’ SGA-8343 is a high performance SiGe
HBT amplifier designed for operation from DC to 6 GHz. This RF
device uses the latest Silicon Germanium Heterostructure Bipolar
Transistor (SiGe HBT) process. The SGA-8343 is optimized
for 3V operation but can be biased at 2V for low-voltage battery
operated systems. The device is easily matched as
Γ
is
very close to 50 ohms. This device provides high gain, low NF,
and excellent linearity at a low cost.
