FEATURES
High Voltage Operation (VDS=28V) GaAs FET
High Gain: 15.5dB(typ.) at Pout=43dBm(Avg.)
Broad Frequency Range : 2110 to 2170MHz
High Reliability
DESCRIPTION
The FLL21E090IY is a high power GaAs FET that offers high efficiency,
ease of matching, greater consistency and broad bandwidth for high
power L-band amplifiers. This device is targeted for high voltage, low
current operation in digitally modulated base station amplifiers. This
product is ideally suited for W-CDMA and Multi-carrier PCS base station
amplifiers while offering high gain, long term reliability and ease of use.
