Product Description
Stanford Microdevices’ SGA-6586 is a high performance
cascadeable 50-ohm amplifier housed in an low-cost
surface-mountable plastic package. Designed for
operation at voltages as low as 5.0V, 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-6586
DC-2500 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-6586 requires only DC
blocking and bypass capacitors for external components.
