ESCRIPTION
:
The
FPD2250
is
an
AlGaAs/InGaAs
pseudomorphic
High
Electron
Mobility
Transistor (PHEMT), featuring a 0.25
µm
by
2250
µm
Schottky barrier gate, defined by high
-resolution stepper-based photolithography.
The recessed
gate structure minimizes
parasitics to optimize performance.
The
epitaxial structure and processing have been
optimized for reliable high-power applications.
The FPD2250 is also available in the low cost
plastic SOT89 package.
