DESCRIPTION
M04
NEC's NE661M04 is fabricated using NEC's UHS0 25 GHz fT
wafer process. With a typical transition frequency of 25 GHz
the NE661M04 is usable in applications from 100 MHz to 10
GHz. The NE661M04 provides excellent low voltage/low cur-
rent performance.
NEC's new low profile/flat lead style "M04" package is ideal for
today's portable wireless applications. The NE661M04 is an
ideal choice for LNA and oscillator requirements in all mobile
communication systems.
