To：SIEMIC （Shenzhen-China）laboratories Declaration Letter For our business issue and marketing requirement, we would like to list below 7 model numbers on the FCC reports, the details difference as following: Differences of Product Series Models Item No. Products Name Product Model Number of PA Unit Power Divider Ty pe Power Combiner Ty pe Number of PA Po we r Supply Number of blower Remarks 1 1.3kW AT S C T V transmitter BGTDV31610 4 One to four Four to one 2 2 The differences of Series products are mainly due to different number of power amplifiers. Different number of power amplifiers causes different dividers, combiners, power amplifier power supplies and fans, while the equipment size and control system remains the same. 2 1.2kW AT S C T V transmitter BGTDV3169 4 One to four Four to one 2 2 3 1kW AT S C T V transmitter BGTDV31611 3 One to three Three to one 2 2 4 750W AT S C T V transmitter BGTDV2862 2 One to two Two to one 1 1 5 500W AT S C T V transmitter BGTDV25612 2 One to two Two to one 1 1 6 300W AT S C T V transmitter BGTDV2365 1 No No 1 1 7 250W AT S C T V transmitter BGTDV2364 1 No No 1 1 Note: Even with the same hardware configuration, the output power of different models could be different due to the different output power of exciters. By adjusting the output of exciters, the RF output power of the transmitter will be changed. This is why the output power of Item 1 and 2 is different even with same hardware configuration. The different power of Item 4, 5, 6, and 7 can be explained in the same way. Thank you!

The transmitter is mainly composed of exciter, switching amplifier, power splitter, power amplifier, power combiner, band-pass filter, collection and control unit, central control unit and power distribution unit. The working principle is that the input TS signal of received programs, after encoding and modulation of exciter, becomes required digital base band signals, which are directly up-converted to RF signals and amplified phase by phase to finally reach output power of digital 1.3kW.
