The NE5510279A is an N-Channel silicon power MOSFET specially designed as the transmission power amplifier for 3.5 V GSM1800 handsets. Dies are manufactured using NEC's NEWMOS technology (NEC's 0.6 m WSi gate lateral MOSFET) and housed in a surface mount package. This device can deliver 32 dBm output power with 45% power added efficiency at 1.8 GHz under the 3.5 V supply voltage, or can deliver 31 dBm output power at 2.8 V by varying the gate voltage as a power control function.
