  • Page 14 Inside each of the 500-watt RMS power amplifiers, the signal passes through an RF attenuator to limit the output power level of the power amplifier and to help buffer any transients that may come into the power amplifier. After attenuation, the signal gets preamplified through a UHFTV- 50 driver amplifier before the signal gets split into (3) signals for final amplification using a 3-way microstrip power divider.

  • Page 16 After amplification, the signal exits the power amplifier enclosure and goes into the filter/coupler enclosure. The two RF signals from each of the TAUD-500 amplifiers (500-watts RMS) get combined by a 2-way, 90 degree combiner via phased cables. The amplified signals are filtered with a bandpass filter and monitored again with another directional coupler before heading out to the customers inline 8VSB reading wattmeter and then to an antenna for broadcast, as depicted in the following filter/coupler block diagram.

  • Page 81 Electrical Service Recommendations Technalogix recommends that a qualified, licensed local electrician be consulted for the required electrical service. We suggest local electricians because: • The personnel knows the local codes • The personnel can be on site readily • You are apt to get better overall support if you give what business you can to local suppliers Technalogix recommends that proper AC line conditioning and surge suppression be provided on the primary AC input to the power amplifier.
