Description
The AFM08P2-000 is a high performance power GaAs
MESFET chip having a gate length of 0.25 µm and a total
gate periphery of 800 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.
