Description
The AFM04P2-000 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 40 GHz,
making it suitable for a wide range of commercial and
military applications in oscillator and amplifier circuits. It
employs Ti/Pd/Au gate metallization and surface
passivation to ensure a rugged, reliable part. Through-
substrate via holes are incorporated into the chip to
facilitate low inductance grounding of the source for
improved high frequency and high gain performance.
