Description

The AFM06P3-212, 213 are high performance power
GaAs MESFET chips in an industry standard ceramic
micro-x package, having a gate length of 0.25 µm and a
total gate periphery of 600 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
employ Ti/Pd/Au gate metallization and surface
passivation to ensure a rugged, reliable part.
