DESCRIPTION
The NE25118 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 4 pin super mini-mold
package, (SOT-343 type). Maximum package height of 1.0
mm makes the NE25118 an ideal device for PCMCIA card
applications.
