ETC SGA-6589

Product Description
SGA-6589
Stanford Microdevices’ SGA-6589 is a high performance
cascadeable 50-ohm amplifier. This RFIC uses the latest
Silicon Germanium Heterostructure Bipolar Transistor (SiGe
HBT) process featuring 1 micron emitters with FT 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-6589 requires only DC blocking
and bypass capacitors for external components.
