Description
The AFM04P3-000 is a high performance power GaAs
MESFET chip having a gate length of 0.25 µm and a total
gate periphery of 400 µm. The device has excellent gain
and power performance through 26 GHz, making it
suitable for a wide range of commercial and military
applications in oscillator and amplifier circuits. The device
employs Ti/Pd/Au gate metallization and surface
passivation to ensure a rugged, reliable part.
