Product Description  
Features  
The SGA7489Z is a high performance SiGe HBT MMIC Amplifier. A Darling-  
ton configuration featuring one-micron emitters provides high FT and  
excellent thermal performance. The heterojunction increases breakdown  
voltage and minimizes leakage current between junctions. Cancellation of  
emitter junction non-linearities results in higher suppression of intermodu-  
lation products. Only two DC-blocking capacitors, a bias resistor, and an  
optional RF choke are required for operation.
