Principle of Operation
The TAV-1000 power amplifier supplies a 1000-watt peak video signal with 10% aural power on any of the VHF
television channels 2 through 13. Please note that channel selection must be made at time of order, as the
transmitter or translator is calibrated and tested to the channel requested and is not field tuneable. The TAV-
1000 power amplifier is a modular solid-state 1000-watt broadcast amplifier utilizing readily available RF
components wherever possible, thus enhancing the serviceability of the equipment. The TAV-1000 features ultra
linear amplification and individual channel RF output bandpass filtering. The amplifier modules are stable for high
reliability and long service life.
The amplification of the TAV-1000 is comprised of (2) TAV-500 500-watt power amplifiers. Firstly, the output of
the modulator or processor gets split into (2) RF signals of equal amplitude. Each output of the 2-way power
divider is then fed into a TAV-500 Power Amplifier. Finally, the outputs of each TAV-500 are combined to
generate 1000-watts of peak visual power in addition to an aural carrier, as seen in the TAV-1000 block diagram.
