4cx12,000a/8989

cHaRacteRistics

The 4CX12,000A/8989 is intended for use in VHF

radio frequency applications. It features an inter-

nal mechanical structure which results in high RF

operating efﬁciency. Low RF losses in this struc-

ture permit operation at full ratings up to 220 MHz.

The 4CX12,000A/8989 has a gain of 18 dB in FM

broadcast service, and is also recommended for

RF linear ampliﬁer service, and for VHF-TV linear

ampliﬁer service. The anode is rated for 12 kilo-

watts of dissipation with forced air-cooling and

incorporates a new highly efﬁcient cooler design,

which signiﬁcantly reduces air pressure and ﬂow
