Datasheet SGA-3563 Datasheet (Stanford Microdevices)

Product Description

Stanford Microdevices SGA-3563 is a high performance
cascadeable 50-ohm amplifier designed for operation at
voltages as low as 3.2V. This RFIC uses the latest Silicon
Germanium Heterostructure Bipolar Transistor (SiGe HBT)
process featuring 1 micron emitters with FT up to 50 GHz.

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-3563 requires only DC blocking and
bypass capacitors for external components.
