FLL1200IU-2
L-Band Medium & High Power GaAs FET FEATURES
* * * * * Push-Pull Configuration High Power Output: 120W (Typ.) High PAE: 44%. Broad Frequency Range: 1800 to 2000 MHz. Suitable for class AB operation.
DESCRIPTION
The FLL1200IU-2 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 PCS/PCN 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. ABSOLUTE MAXIMUM RATINGS (Ambient Temperature Ta=25C)
