NTE77
Silicon NPN Transistor
Broadband CATV Driver
Description:
The NTE77 is an NPN transistor in a TO39 type case designed to be utilized in broadband and linear
amplifier circuitry requiring low noise and low intermodulation distortion. This device is suitable for
use in CATV driver stages in trunk line, bridger, and line extender amplifiers.
