DESCRIPTION
NEC's NE678M04 is fabricated using NEC's HFT3 wafer
process. Withatransitionfrequencyof12GHz, theNE678M04
isusableinapplicationsfrom100MHzto3GHz.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.
