III-2
Principle of Operation
The TAV-25 power amplifier supplies a 25-watt peak video signal with an aural carrier level 10 to 13 dB
below visual carrier (dBc) 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-25 power amplifier is a modular
solid-state 25-watt broadcast amplifier utilizing readily available RF components wherever possible,
thus enhancing the serviceability of the equipment.
The TAV-25 is comprised of a VHFTV-25-L pallet for low-band VHF frequencies or VHFTV-25-H pallet
for high-band VHF frequencies.
The TAV-25 features ultra linear amplification and individual channel RF output bandpass filtering. The
amplifier modules are stable for high reliability and long service life.
