DESCRIPTION
The 2SC4703 is designed for low distortion, low noise RF amplifier
operating with low supply voltage (V
CE
= 5 V). This low distortion
characteristic makes it suitable for CATV, tele-communication and other
use. It employs surface mount type plastic package, Power Mini Mold
(SOT-89).
FEATURES
Low distortion at low supply voltage.
