ABSOLUTE MAXIMUM RATING (Ambient Temperature Ta=25C)
Fujitsu recommends the following conditions for the reliable operation of GaAs FETs:
1. The drain-source operating voltage (VDS) should not exceed 10 volts.
2. The forward and reverse gate currents should not exceed 80.4 and -17.4 mA respectively with
gate resistance of 25.
3. The operating channel temperature (Tch) should not exceed 145C.

DESCRIPTION
The FLL300IL-1, FLL300IL-2, FLL300IL-3 are Power GaAs FETs that are
specifically designed to provide high power at L-Band frequencies with
gain, linearity and efficiency superior to that of silicon devices. The
performance in multitone environments for Class AB operation make
them ideally suited for base station applications.
Fujitsu's stringent Quality Assurance Program assures the highest
reliability and consistent performance.
