DESCRIPTION
19 (3 PIN ULTRA SUPER
MINI MOLD)
18 (SOT 343 STYLE)
The family of high frequency, low cost, surface mount
devices are well suited for portable wireless communications
and cellular radio applications.
30 (SOT 323 STYLE)
33 (SOT 23 STYLE)
NT
The NE685 series of high fT (12 GHz) devices is suitable for
very low voltage/low current, low noise applications. These
products are ideal for applications up to 2.4 GHz where low
cost, high gain, low voltage, and low current are prime concerns.
