Product Features

Applications

Electrical Specifications at Ta = 25C

Stanford Microdevices’ SGA-5486 is a high performance

cascadeable 50-ohm amplifier designed for operation at

voltages as low as 3.5V. This RFIC uses the latest Silicon

Germanium Heterostructure Bipolar Transistor (SiGe HBT)

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-5486 requires only DC

blocking and bypass capacitors for external components.
