III-3 Block Diagram The RF signal enters through the RF Input connector on the power amplifier enclosure from the modulator or processor. It then 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 the driver pallet before the signal gets split into (2) signals for final amplification. The output of the (2) final amplifier pallets get combined and passes through an isolator and a bandpass filter. Finally, the signal passes through a dual directional coupler for monitoring purposes before heading out to an antenna for broadcast. To Wattmeter and Antenna A=14dB min. A=14dB min. A=+38dB min.

III-2 Principle of Operation The TAU-500 power amplifier supplies a 500-watt 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 TAU-500 power amplifier is a modular solid-state 500-watt broadcast amplifier utilizing readily available RF components wherever possible, thus enhancing the serviceability of the equipment. The TAU-500 is comprised of a TECH-30U driver pallet and (2) P300 final pallets that are combined to create 500 watts of peak visual power in addition to the aural carrier power. The TAU-500 features ultra linear amplification and individual channel RF output bandpass filtering. The amplifier modules are stable for high reliability and long service life.

Should a different modulator or processor be used, specifications could vary. For this reason, we recommend that any different modulator/processor be shipped to Technalogix so the system can be matched and set up optimally. In addition, the audio/video ratio the input to the power amplifier needs to be –10 dB in order for the software and LCD readout to be accurate.

This stage typically draws 2.5 Adc quiescent and a maximum drain current of 5 Adc. The second stage is a linear class AB stage with a typical gain of 13 dB. This stage typically draws 1.0 Adc quiescent and a maximum drain current of 10 Adc. The currents on both stages can be found by measuring the voltage drop across the +30 Vdc input and the I sense connector. The resistance separating these connections is 0.01 ohms, providing a 10 mV per ampere ratio. The P300-UHF pallets used in the final amplification stage use LDMOS (Laterally Diffused Metal Oxide Semiconductor) technology. LDMOS technology offers higher gain, efficiency and linearity over standard MOSFET and Bipolar devices and enhances ruggedness and reliability. LDMOS transistors have the added advantage of not having BEO (Beryllium Oxide) in their construction. The P300-UHF amplifier pallets have a typical gain of 15dB (14dB minimum) and draw no more than 23Adc. Currents for these pallets must be measured with an ammeter in series with the power supply lead. Each of the amplifier pallets is connectorized to optimize servicing and accessibility. All amplifier pallets must have the transistor drain voltages reach at least 26Vdc before the RF drive is applied. IV-2 Splitter/Combiner The splitter and combiner are used to split the RF signal into, and combine the amplified RF signal out of the (2) final amplifier pallets. The connectorized designs are based on the simple isolated Wilkinson combiner design. Due to its electrical and mechanical symmetry, the Wilkinson design’s performance over moderate bandwidths is superior t…

This is also the average power measured during a synchronizing pulse. Requirement: Specified by the manufacturer as 500 watts peak. Method: The visual carrier is modulated with a sync and blanking signal. The aural carrier is not present. An average reading RF wattmeter is placed between the transmitter output (directly on the directional coupler’s N connector on the back panel) and the 50 O dummy load. The peak visual power is the measured average power multiplied by a factor of 1.68. Due to the low level of the RF Output signal, a spectrum analyzer was used to measure the visual output rating. Measurement: The rated visual output power is 500 watts peak. 5 6 Visual Power Adjustment Capability Definition: The peak output power adjustment ca…
