FLL800IQ-2C
L-Band High Power GaAs FET
DESCRIPTION
The FLL800IQ-2C is a 80 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 W-CDMA and IMT 2000 base
station amplifiers as it offers high gain, long term reliability and ease of use.
FEATURES
Push-Pull Configuration
High Power Output: 80W (Typ.)
High PAE: 50% (Typ.)
Broad Frequency Range: 2100 to 2200 MHz.
Suitable for class AB operation.
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 (VDS) should not exceed 12 volts.
2. The forward and reverse gate currents should not exceed 176 and -51.8 mA respectively with
gate resistance of 10
.
3. The operating channel temperature (Tch) should not exceed 145C.
