NTE329
Silicon NPN Transistor
RF Power Amp, CB
Description:
The NTE329 is designed primarily for use in largeâsignal output amplifier stages. Intended for use
in CitizenâBand communications equipment operating to 30MHz. High breakdown voltages allow a
high percentage of upâmodulation in AM circuits.
