Push-Pull Configuration
High Power Output: 240W (Typ.)
Broad Frequency Range: 2100 to 2200 MHz.
Suitable for class AB operation.
DESCRIPTION
The FLL2400IU-2C is a 240 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
鈥?Solid State Base-Station Power Amplifier.
鈥?W-CDMA and IMT 2000 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 367 and -161 mA respectively with
gate resistance of 1.5鈩?
3. The operating channel temperature (Tch) and case temperature (Tc) should not exceed 145擄C and 80擄C respectively.
