FLL357ME
L-Band Medium & High Power GaAs FET
DESCRIPTION
The FLL357ME is a Power GaAs FET that is 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. This device is assembled in hermetic
metal/ceramic package.
Fujitsu’s stringent Quality Assurance Program assures the highest
reliability and consistent performance.

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 19.4 and -2.0 mA respectively with
gate resistance of 100.
3. The operating channel temperature (Tch) should not exceed 145°C.
