3cW2500c7 / yu-157
The 3CW2500C7/YU-157 is a rugged coaxial base
power triode designed for use as a cathode driven
Class AB2 or Class C amplifier. It is recommended
for VHF or UHF service as a linear amplifier, power
amplifier, or pulse amplifier. Linearity and power
gain are both excellent due to the low ratio of grid
to plate current, and the relatively high amplifi-
cation factor. Low grid interception of available
emission current is due to the beam forming ge-
ometry of the special grid and cathode design.
