Blue Bell PA, 19422 APPLICATION FOR TYPE ACCEPTANCE FCC IDENTIFICATION NUMBER:BQMNH6050E DATE:MAY 24, 2000 2 APPLICABLE FCC PARAGRAPH:2.983 SUB-PARAGRAPH:(b)(c) PARAGRAPH TITLE:IDENTIFICATION OF EQUIPMENT •••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••• The following is the description of the Acrodyne model number NH6050E equipment for which type acceptance is sought: INPUT:Baseband video and audio. OUTPUT:Any single TV channel between 470 and 806 MHz (channels 14 to 69). POWER:5000 watts peak of sync visual power maximum, 500 watts average aural power. The equipment identification plate is shown in paragraph section 2.983(f) in this application. The location of the identification plate is shown in paragraph section 2.983(g) in this application. Quantity production of the NH6050E is planned. APPLICATION FOR TYPE ACCEPTANCE FCC IDENTIFICATION NUMBER:BQMNH6050E DATE:MAY 24, 2000 3 APPLICABLE FCC PARAGRAPH:2.983 SUB-PARAGRAPH:(d) PARAGRAPH TITLE:TECHNICAL DESCRIPTION •••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••• 1.The NH6050E television transmitter is used to broadcast C3F visual and F3E aural emissions. 2.The output frequency range of the NH6050E is from 470 to 806 MHz. 3.The power rating of the output of the NH6050E is between 2,500 and 5,000 watts peak of sync visual, and 250 and 500 watts average aural. Varying the output level is accomplished by varying the output power of the exciter section. 4.The maximum power rating of the NH6050E is 5000 watts peak of sync visual power and 500 watt average aural. Proper operation is excess of 100 percent is limited by final power amplifier non-linearities. 5.The NH6050E final amplifier section is made up of three visual amplifier modules and one aural amplifier module. Each of these modules contains eight LDMOS RF power transistors operating in parallel. Power supply voltage is 30 VDC, provided by a power supply integrated into the module. A device data sheet is included in section 75.750( c)(6). 6.7.8. The function of each active circuit device is explained in the technical description sections of the instruction manual included. 9.The transmitter tune up procedure is contained in the NH6050E technical manual supplied. No tuning is required for the RF stages as they are all broadband stages. 10.The output frequency of the NH6050E is determined by the stability of the synthesizer reference oscillator. Both the visual IF oscillator and the IF-to RF conversion oscillator are phase locked to the same reference oscillator. The aural IF is phase locked to the visual IF carrier. The description of these circuits is contained in the instruction manual supplied. 11.The linearity of the output amplifier RF devices requires the use of a output harmonic filter to suppress spurious radiation below that required by the applicable section of the rules. 12.This section requiring a description of any digital modulation techniques is not applicable to the type acceptance sought.
