Stanford Microdevices' SGA-2386 is a high performance
cascadeable 50-ohm amplifier designed for operation from
a 2.7-volt supply. This RFIC uses the latest Silicon
Germanium Heterostructure Bipolar Transistor (SiGe HBT)
process featuring 1 micron emitters with F
T
up to 65 GHz.
This circuit uses a darlington pair topology with resistive
feedback for broadband performance as well as stability
over its entire temperature range. Internally matched to
50 ohm impedance, the SGA-2386 requires only DC
blocking and bypass capacitors for external components.
