Description
The P35-4721-000-200 is a high performance Gallium Arsenide Power Amplifier MMIC. It is
primarily intended for wireless applications in the 5 - 6 GHz bandwidth such as U-NII (Unlicensed
National Information Infrastructure) and HIPERLAN (High Performance Local Area Network).
The three-stage amplifier requires plus and minus 5V power supplies. Also incorporated into the
design is the ability to switch between four gain states, High, Medium1, Medium2 and Low Gain, as well
as a chip standby mode which typically draws 0.1mA. In addition the design has been optimised for
the effects of a single bondwire at both the input and output.
The die is fabricated using MCL's F20 Gallium Arsenide MESFET MMIC process and is fully protected
using Silicon Nitride passivation for excellent performance and reliability.
