FLL120MK
L-Band Medium & High Power GaAs FET
DESCRIPTION
The FLL120MK 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.
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 26.8 and -5.8 mA respectively with
gate resistance of 50Ω.
3. The operating channel temperature (Tch) should not exceed 145°C.
