DESCRIPTION
The NE678M04 is fabricated using NEC's HFT3 wafer pro-
cess. With a transition frequency of 12 GHz, the NE678M04 is
usableinapplicationsfrom100MHzto3GHz. TheNE678M04
provides P1dB of 18 dBm, even with low voltage and low
current, making this device an excellent choice for the driver
stage for mobile or fixed wireless applications.
