DESCRIPTION
The FLL1200IU-3 is a 120 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 Wireless Local Loop (WLL) base
station amplifiers as it offers high gain, long term reliability and ease of use.
APPLICATIONS
• Solid State Base-Station Power Amplifier.
• WLL Communication Systems.

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 156.0mA and -57.6mA respectively with
gate resistance of 10Ω.
3. The operating channel temperature (Tch) should not exceed 145°C.
