3.2 V OPERATION SILICON RF POWER LDMOS FET

FOR GSM/DCS DUAL-BAND PHONE TRANSMISSION AMPLIFIERS

DESCRIPTION

The NE5520379A is an N-channel silicon power MOS FET specially designed as the transmission power amplifier

for 3.2 V GSM 900 handsets. Dies are manufactured using our NEWMOS technology and housed in a surface mount

package. This device can deliver 34.6 dBm output power with 68 power efficiency at 915 MHz under the 2.8 V

supply voltage.
