Product Description
The SGA3486Z is a high performance SiGe HBT MMIC Amplifier. A Darling-
ton configuration featuring one micron emitters provides high F_T 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.
