DESCRIPTION
The family of high frequency, low cost, surface mount
devices are well suited for portable wireless communications
and cellular radio applications.
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 con-
cerns.
Notes: 1. Precaution: Devices are ESD sensitive. Use proper handling procedures.
2. Electronic Industrial Association of Japan.
3. Pulsed measurement, PW350 μs, duty cycle 2%.
4. The emitter terminal should be connected to the ground terminal
of the 3 terminal capacitance bridge.
