SILICON TRANSISTOR
2SC4094
MICROWAVE LOW NOISE AMPLIFIER
NPN SILICON EPITAXIAL TRANSISTOR
4 PINS MINI MOLD
DESCRIPTION
The 2SC4094 is an NPN epitaxial silicon transistor designed for use in
low-noise and small signal amplifiers from VHF band to UHF band. Low-
noise figure, high gain, and high current capability achieve a very wide
dynamic range and excellent linearity.
proprietary new fabrication technique.
This achieved by direct nitride
