Text preview for : RDA03(2-4 GHz Driver Amp).pdf part of Rficsolutions.Inc RDA03 The RDA03 is a 2.0 to 4.0 GHz, high gain Driver
Amplifier. It provides very good gain flatness over
the band. It requires +3.3 Volt supply.
It has tunability by having some off chip
components. It has the option to optimize externally
with off chip interstage match.
The die area of RDA03 is 1.0 mm X 0.5 mm
