Product Description
Stanford Microdevices SGA-0163 is a high performance
cascadeable 50-ohm amplifier designed for operation at
voltages as low as 2.1V. This RFIC uses the latest Silicon
Germanium Heterostructure Bipolar Transistor (SiGe HBT)
process featuring 1 micron emitters with F
T
up to 50 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-0163 requires only DC blocking and
bypass capacitors for external components.
