The MAAD-010305 is fabricated as a monolithic
GaAs integrated circuit using a mature pHEMT
process. The process features full chip passivation
for performance and reliability.
Pin Configuration
This device is ideally suited for use where high
accuracy, very low power consumption and low
intermodulation products are required.

Handling Procedures
Please observe the following precautions to avoid
damage:
Static Sensitivity
Gallium Arsenide Integrated Circuits are sensitive
to electrostatic discharge (ESD) and can be
damaged by static electricity. Proper ESD control
techniques should be used when handling these
devices.
Plated Vias are .024 diameter
