Preliminary  
Product Description  
SGA-7489  
Stanford Microdevices’ SGA-7489 is a high performance  
cascadeable 50-ohm amplifier designed for operation at 5  
Volts DC# This RFIC uses the latest Silicon Germanium  
Heterostructure Bipolar Transistor (SiGe HBT) process  
featuring 1 micron emitters with FT up to 50 GHz#  
DC-3000 MHz Silicon Germanium  
HBT Cascadeable Gain Block  
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-7489 requires only DC blocking  
and bypass capacitors and a bias inductor for external  
components# Frequency performance may be extended using  
the 2 GHz application circuit shown on sheet 5#  
Product Features
