The 4CX20,000E is a ceramic/metal power tet-

rode intended for use as a VHF power ampliﬁer. It

features a type of internal mechanical structure,

which results in rf operating efﬁciency. Low rf

losses in this structure permit operation at full rat-

ings to 110 MHz.

The 4CX20,000E provides high gain in FM Broad-

cast service and is also recommended for rf linear

power ampliﬁer service, including IBOC digital

transmission. The anode is rated for 20 kilowatts

of dissipation with forced-air cooling and incor-

porates a compact, highly efﬁcient cooler of new

design
