SGA-5486 Datasheet, PDF (1/7 Pages) Stanford Microdevices – DC-2400 MHz 3.5V SiGe Amplifier

Product Description
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)
process featuring 1 micron emitters with FT up to 65 GHz.
Preliminary
SGA-5486
DC-2400 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-5486 requires only DC
blocking and bypass capacitors for external components.
