Principle of Operation
The TAUD-40 power amplifier supplies a 130-watt P1dB peak video signal with an aural carrier level
10 to 13 dB below visual carrier (dBc) on any of the UHF television channels 14 through 69. 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 TAUD-40 power amplifier is a
modular solid-state 100-watt broadcast amplifier utilizing readily available RF components wherever
possible, thus enhancing the serviceability of the equipment.
The TAUD-40 is comprised of a UHFTV-10 driver and a UHFTV-150 final amplifier. The unique zero
sync compression technology ensures digital ready operation.
The TAUD-40 features ultra linear amplification and individual channel RF output bandpass filtering.
The amplifier modules are stable for high reliability and long service life.
