NE687M23 Datasheet, PDF (1/2 Pages) NEC – NPN SILICON TRANSISTOR
PRELIMINARY DATA SHEET
NPN SILICON TRANSISTOR NE687M23
FEATURES
• NEW MINIATURE M23 PACKAGE:
– World's smallest transistor package footprint —
leads are completely underneath package body
– Low profile/0.55 mm package height
– Ceramic substrate for better RF performance
• HIGH GAIN BANDWIDTH PRODUCT:
fT = 5.5 GHz
• LOW NOISE FIGURE:
NF = 1.5 dB at 2 GHz
DESCRIPTION
The NE687M23 transistor is designed for low noise, high gain,
and low cost requirements. This high fT part is well suited for
very low voltage/low current designs for portable wireless
communications and cellular radio applications. NEC's new
low profile/ceramic substrate style "M23" package is ideal for
today's portable wireless applications. The NE687 is also
available in six different low cost plastic surface mount pack-
age styles.
