SGA-2363 Datasheet, PDF (1/7 Pages) Stanford Microdevices – DC-2800 MHz Silicon Germanium HBT Cascadeable Gain Block

Product Description
Stanford Microdevices’ SGA-2363 is a high performance
cascadeable 50-ohm amplifier designed for operation from
a 2.7-volt supply. This RFIC uses the latest Silicon
Germanium Heterostructure Bipolar Transistor (SiGe HBT)
process featuring 1 micron emitters with FT up to 50 GHz.
Preliminary
SGA-2363
DC-2800 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-2363 requires only DC
blocking and bypass capacitors for external components.
