Description
The AFM04P3-212, 213 are high performance power
GaAs MESFET chips having a gate length of 0.25 µm and
a total gate periphery of 400 µm. These devices have
excellent gain and power performance through 26 GHz,
making them suitable for a wide range of commercial and
military applications in oscillator and amplifier circuits. They
also have excellent noise performance and can be used
in the first and second stage of low noise amplifier design.
The AFM04P3 employs Ti/Pd/Au gate metallization and
surface passivation to ensure a rugged, reliable part.
