DESCRIPTION
The NE253 is an 800
碌m
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 (sur-
face mount) package.
