4cx20,000a/8990

cHaRacteRistics

The 4CX20,000A/8990 is a power tetrode intended

for use in audio or radio frequency applications. It

features an internal mechanical structure which

results in high RF operating efﬁciency. Low RF

losses in this structure permit operation at full

ratings up to 110 MHz and at reduced ratings to

220 MHz. The 4CX20,000A/8990 has a gain over

18 dB in FM broadcast service, and is also recom-

mended for radio frequency linear power ampliﬁer

service, and for VHF-TV linear ampliﬁer service.

The anode is rated for 20 kW of dissipation with
