FLL600IQ-3
L-Band Medium & High Power GaAs FET
DESCRIPTION
The FLL600IQ-3 is a 60 Watt GaAs FET that employs a push-pull design that
offers ease of matching, greater consistency and a broader bandwidth for high
power L-band amplifiers. This product is targeted to reduce the size and complexity
of highly linear, high power base station transmitting amplifiers. This new product is
uniquely suited for use in WLL and MMDS base station amplifiers as it offers high
gain, long term reliability and ease of use.
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 12 volts.
2. The forward and reverse gate currents should not exceed 78 and -32 mA respectively with
gate resistance of 25Ω.
3. The operating channel temperature (Tch) should not exceed 145°C.
