NE25139 mesfet equivalent, dual-gate gaas mesfet.
* SUITABLE FOR USE AS RF AMPLIFIER IN UHF TUNER
* LOW CRSS: 0.02 pF (TYP)
* HIGH GPS: 20 dB (TYP) AT 900 MHz
* LOW NF: 1.1 dB TYP AT 900 MHz
* LG1 = 1.
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 MESFET.
