FLL1500IU-2C
L-Band High Power GaAs FET
FEATURES
• Push-Pull Configuration
• High Power Output: 150W (Typ.)
• High PAE: 48% (Typ.)
• Broad Frequency Range: 2100 to 2200 MHz.
• Suitable for class AB operation.
DESCRIPTION
The FLL1500IU-2C is a 150 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 well suited for use in W-CDMA and IMT 2000 base station
amplifiers as it offers high gain, long term reliability and ease of use.
APPLICATIONS
• Solid State Base-Station Power Amplifier.
• W-CDMA and IMT 2000 Communication Systems.

Eudyna recommends the following conditions for the reliable operation of GaAs FETs:
1. The drain-source operating voltage (V ) should not exceed 12 volts.
DS
2. The forward and reverse gate currents should not exceed 353 and -103.6 mA respectively with
gate resistance of 10Ω.
3. The operating channel temperature (T ) should not exceed 145°C.
