SILICON POWER MOS FET
NE552R679A
3.0 V OPERATION SILICON RF POWER LD-MOS FET
FOR 460 MHz 0.6 W TRANSMISSION AMPLIFIERS
DESCRIPTION
The NE552R679A is an N-channel silicon power laterally diffused MOS FET specially designed as the
transmission power amplifier for 3.0 V FRS (Family Radio Service). Dies are manufactured using our NEWMOS2
technology (our WSi gate lateral-diffusion MOS FET) and housed in a surface mount package. This device can
deliver 28.0 dBm output power with 60% power added efficiency at 460 MHz under the 3.0 V supply voltage.
