Innovator CHV0TD/RD-1 through CHV4TD/RD ATSC Transmitter/Regenerative Translator Board Descriptions The Overdrive protection looks at a sample of the RF signal that is applied to J1 of the board. The peak level of this signal is detected and can be measured on TP1. This voltage is applied to a comparator with the threshold set by R38. If this threshold is exceeded, the ALC circuit mutes then ramps up to try again. This circuit also works in manual gain as well.

Innovator CHV0TD/RD-1 through CHV4TD/RD ATSC Transmitter/Regenerative Translator Board Descriptions The 50 Watt Amplifier Pallet, Italmec is made by Italmec for Axcera’s use. This broadband amplifier operates in the frequency range of 170 to 240 MHz. The amplifier is capable of delivering a maximum output power of 25 Watts digital, with an amplification factor of approximately 24 dB. The RF output of the pallet is wired to J2 the RF output jack of the 20W driver amplifier assembly.
