PRELIMINARY DATA SHEET
NPN SILICON TRANSISTOR NE688M23
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 = 9.5 GHz
• LOW NOISE FIGURE:
NF = 1.7 dB at 2 GHz
• HIGH COLLECTOR CURRENT:
IC MAX = 100 mA
DESCRIPTION
The NE688M23 transistor is designed for low cost amplifier
and oscillator applications. Low noise figure, high gain and high
current capability equate to wide dynamic range and excellent
linearity. NEC's new low profile/ceramic substrate style "M23"
package is ideal for today's portable wireless applications. The
NE688 is also available in chip and six different low cost plastic
surface mount package styles.
