ETC SGA-5486

Preliminary
Product Description
SGA-5486
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.
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.

Function
Description
RF IN
RF input pin. This pin requires the use of
an external DC blocking capacitor
chosen for the frequency of operation.
GND
Connection to ground. Use via holes for
best performance to reduce lead
inductance as close to ground leads as
possible.
RF OUT/ RF output and bias pin. DC voltage is
BIAS
present on this pin, therefore a DC
blocking capacitor is necessary for
proper operation.
