SERIES

FEATURES

• LOW COST

• HIGH GAIN BANDWIDTH PRODUCT:

• LOW COLLECTOR TO BASE TIME CONSTANT:

The NE944 series of NPN silicon epitaxial bipolar transistors

is intended for use in general purpose UHF oscillator and

mixer applications. It is suitable for automotive keyless entry

and TV tuner designs.

The device features stable oscillation and small frequency

drift during changes in the supply voltage and over the

ambient temperature range.
