Description
The Eleflow 2SC1972 is a silicon NPN epitaxial planar type transistor designed
for RF power amplifiers within the VHF band, ideal for mobile radio applications.
Features
• High power gain: Gpe ≥ 7.5dB
@Vcc = 13.5V, Po = 14W, f = 175MHz
• Emitter ballasted construction for reliability and performance.
• Manufactured incorporating recyclable RoHS compliant materials.
• Ability to periodically withstand in excess of 20:1 VSWR load when
operated at Vcc = 15.2V, Po = 18W, f = 175MHz.
Application
10 to 14 watts output power amplifier applications within the VHF band.
