| PRELIMINARY DATA SHEET NPN SILICON TRANSISTOR NE685M23 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 = 12 GHz LOW NOISE FIGURE: NF = 1.5 dB at 2 GHz OUTLINE DIMENSIONS (Units in mm) PACKAGE OUTLINE M23 0.5 * * 1 0.25 1.0 0.4 DESCRIPTION The NE685M23 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 NE685 is also available in six different low cost plastic surface mount package styles. 0.6 0.15 2 3 0.25 0.2 0.15 BOTTOM VIEW PIN CONNECTIONS 1. Collector 2. Emitter 3.
