Product Description
Stanford Microdevices SGA-4586 is a high performance
cascadeable 50-ohm amplifier designed for operation at
voltages as low as 3.6V. 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-4586
DC-4000 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-4586 requires only DC blocking
and bypass capacitors for external components.
