N-CHANNEL SILICON POWER MOS FET

POWER AMPLIFIER FOR GSM CLASS 4 HANDSETS

DESCRIPTION

The NE5500434 is an N-channel silicon power MOS FET specially designed as the transmission power amplifier

for GSM class 4 handsets. Dies are manufactured using our NEWMOS technology (our 0.6 μm WSi gate lateral MOS

FET), housed in a surface mount 3-pin power minimold (34 PKG) (SOT-89 type) package. The device can deliver 35

dBm output power with 63 power added efficiency at 900 MHz under the 4.8 V supply voltage.

The NE5500434 also can deliver 31.5 dBm output power with 60 power added efficiency at 3.6 V.

FEATURES
