DESCRIPTION AND APPLICATIONS
The FPDA200V is an Aluminum Gallium Arsenide / Indium Gallium Arsenide (AlGaAs/InGaAs)
Pseudomorphic High Electron Mobility Transistor (PHEMT), utilizing an Electron-Beam direct-
write 0.25
µm
by 200
µm
Schottky barrier gate. The recessed “mushroom” gate structure minimizes
parasitic gate-source and gate resistances. The epitaxial structure and processing have been
optimized for high dynamic range.
Typical applications include high dynamic range driver stages for commercial applications including
wireless infrastructure systems, broad bandwidth amplifiers, and optical systems.
Source vias have been added for improved performance and assembly convenience. Each via hole
has 0.02 nH of inductance. Additionally, the via holes remove the need for source bond wires,
meaning only two bond wires are required for assembly. Because the via connects the source pad to
the backside metallization, self-bias configurations should be designed with caution.
