DESCRIPTION
The NE678M04 is fabricated using NEC's HFT3 wafer pro-
cess. With a transition frequency of 12 GHz, the NE678M04 is
usable in applications from 100 MHz to 3 GHz. The NE678M04
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.
The NE678M04 is housed in NEC's new low profile/flat lead
style "M04" package
HIGH GAIN BANDWIDTH:

= 13 dB at 1.8 GHz
NEW LOW PROFILE M04 PACKAGE:
SOT-343 footprint, with a height of only 0.59 mm
Flat lead style for better RF performance
