ATF-541M4 Typical Performance Curves, continued

Notes:

1. Input tuned for minimum NF and the output tuned for maximum OIP3

using an InterContinental Microwave (ICM) test fixture, double stub

tuners and bias tees.

2. Gamma out is the reflection coefficient of the matching circuit presented

to the output of the device.
