Power Amplifier 2 Combiner 3 Pallets PA-25-VHF-H

III-1 Section III - Overview Standard Features • Narrow output bandpass filter allows adjacent channel operation • Front panel Liquid Crystal Display (LCD) to monitor forward and reflected RF power, and DC voltage • Microcontroller-based monitoring and control ensures amplifier will never be overdriven and high VSWR will not damage amplifier • AC circuit breaker on back panel to eliminate replacement of fuses • All aluminium enclosure maintains power amplifier’s light weight • Simple design using commonly available parts ensures reliable operation • Predominate and third-order intermodulation distortion exceeds Industry Canada and FCC specification. III-2 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. III-3 TAV-1000 block diagram PDF inserted here. III-4 Inside each 500-watt power amplifier, the signal gets split into (2) signals for final amplification using a 2-way Wilkinson power divider. The final amplification stage is comprised of (2) P400-VHF- L or (2) P400-VHF-H final amplifiers, for low or high band VHF, respectively. The outputs of the (2) final amplifier pallets are combined with a 2-way Wilkinson combiner and pass through a dual directional coupler for protection and monitoring purposes, as illustrated in the following TAV-500 block diagram. III-5 TAV-500 block diagram PDF inserted here III-6 After amplification, the signal exits the power amplifier enclosure and goes into the combiner/filter enclosure, where the signals from each 500-watt amplifier are combined. After combining, the amplified signals are filtered with a bandpass filter and monitored again with another directional coupler before heading out to an antenna for broadcast, as depicted in the following combiner block diagram. III-7 Combiner block diagram PDF inserted here. III-8 Specifications The following specifications were taken with a Technalogix modulator/processor. 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. All specifications below were taken with the audio/video ratio set -10dB. RF Characteristics Frequency range any specified VHF Channel 2 to 13 Frequency Response (one channel) ±0.5 dB Frequency Stability ±250 Hz Selectivity 60 dB (adjacent channel) Minimum Input Level 0 dBmV Rated Visual Output Power 1000 Watts Rated Aural Output Power 10% of peak visual power IF Output Level -12 dBm nominal Input Impedance 75 Ohms Output Impedance 50 Ohms Harmonics > 60 dB below rated power Predominant Intermodulation Distortion dBc = decibels below visual carrier + 920 kHz > -53 dBc - 920 kHz > -53 dBc + 2.66 MHz > -53 dBc - 2.66 MHz > -53 dBc + 5.42 MHz > -53 dBc + 7.16 MHz > -53 dBc 3 rd Order Intermodulation Distortion - 4.5 MHz > -60 dBc + 9.0 MHz > -60 dBc All others > -60 dBc Spurious Emissions > -60 dBc NTSC Video Characteristics Input Level to modulator (for 87.5% modulation) 1.0 V PP (100IRE + 40IRE sync) Differential Phase (at 87.5% modulation) ±2 Degrees Differential Gain (at 87.5% modulation) 2% Group Delay < ±40 nS Video Group Delay Pre-emphasis Conforms to IC/FCC specifications K-Factor 1.9% for 2T Pulse Hum and Noise > 60 dB below rated power III-9 Aural Characteristics Input Level for 25 kHz Deviation 0.3 V PP Frequency Response (Standard Pre-emphasis) ±1 dB Harmonic Distortion (25 kHz Deviation) < 1% 50 Hz to 15 kHz Amplitude Modulation Noise > 50 dB Frequency Modulation Noise > 60 dB Intercarrier Stability ±250 Hz Physical Characteristics Power Requirements Power Supply 230 V AC , 30 A AC Combiner / Filter 115 V AC , 2 A AC Operating Temperature Range 0°C to 50°C Dimensions TAV-500 Power Amplifier (each) W-19" flange (17” encl.) , D-25", H-8 3/4” (5U) Combiner / Filter W-19" flange (17” encl.) , D-25", H-8 3/4” (5U)

August 17, 2004 This report is in support of an application by Technalogix Ltd. for certification of transmitting equipment used for VHF Band III television systems (170-230 MHz). Specifically, Technalogix is requesting certification of the Technalogix TXV-1000 VHF Band III television transmitter. The TXV-1000 Band III supplies a 1000-watt peak video signal in addition to 10% aural power on any of the VHF television channels 7 through 13. Additionally, the control system allows the user to run 110% of rated power (1,100-watts peak) before the overdrive monitor shuts the system down. The video and audio are amplified with a common amplifier chain. Tests were conducted on production models of the equipment on location at Technalogix: #4, 8021 Edgar Industrial Place Red Deer, Alberta Canada T4P 3R3 403.347.5400 ph 403.347.7444 fx All tests were carried out on representative channels in the VHF Band III in accordance with FCC Part 74. The results in the attached documentation show that the equipment meets or exceeds the required specifications. Included with the documentation is: • Drawing of the FCC label that will be attached to the equipment • Attestation statement • Test report • RF exposure statements • Technalogix user manual. The user manual includes block diagrams of the various systems and sub-systems, schematics and printed circuit board component outlines for the amplification and control sections, specifications, and construction photos. The emission designators for Part 74 transmitters are 5M75C3F (for visual) and 250KF3E (for aural). Technalogix Ltd. #4 – 8021 Edgar Ind.

This is also the average power measured during a synchronizing pulse. Requirement: Specified by the manufacturer as 1,000 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 Ù dummy load. The peak visual power is the measured average power multiplied by a factor of 1.68. Measurement: The rated visual output power is 1,000 watts peak. 5 TXV 1000 - Full Power Visual Power Output Rating 6 TXV 1000 – Quarter Power 7 Visual Power Adjustment Capability Definition: The peak output power adjustment capability is the manual range by which the peak visual output power can be maintained within predetermined limits. Requirement: FCC – The transmitter shall be adjustable to 80%, 100%, and 110% of peak visual power simply for the calibration of meters [section 73.663]. Except as operated in a reduced power operation, the visual output power of a TV transmitter or translator must be maintained as near as practicable to the authorized transmitter output power and may not be less than 80% nor more than 110% of authorized power [section 73.1560(c)] 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 Ù dummy load. The peak visual power is the measured average power multiplied by a factor of 1.68. While observing the external wattmeter, the output power is varied to ensure that is adjustable over the proper ranges. Measurement: Upper limit of visual output power adjustment 110 % Lower limit…
