ABSOLUTE MAXIMUM RATINGS (Ambient Temperature Ta=25

°C)

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 54.4 and -17.4 mA respectively with

gate resistance of 25

Ω.

3. The operating channel temperature (Tch) should not exceed 145°C.

FLL400IP-2

L-Band Medium & High Power GaAs FET

DESCRIPTION

The FLL400IP-2 is a 35 Watt GaAs FET that employs a push-pull design which

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.

FEATURES

• Push-Pull Configuration

• High Power Output: 35W (Typ.)

• High PAE: 44% (Typ.)

• Broad Frequency Range: 800 to 2000 MHz.

• Suitable for class A operation at 10V

and class AB operation at 12V
