DESCRIPTION

Drain to Source Voltage, VDS (V)
The NE251 is a dual gate GaAs FET designed to provide
flexibility in its application as a mixer, AGC amplifier, or low
noise amplifier. As an example, by shorting the second gate
to the source, higher gain can be realized than with single gate
MESFETs. This device is available in a mini-mold (surface
mount) package.
