I am putting together a UHF repeater and have a TLE1713A on hand. I need clarification on a few things so that i don't end up with a fried amp when I power it up.
What i have gleaned from various sources thus far: 1. Rated for 2 watts input max to give about 75-90 watts out. 2. Designed for 450-470 MHz but works just fine down to about 440. 3. It may be advisable to operate it at reduced voltage. 11-12V rather than 13.8V. 4. If it fails, junk it. Difficult to repair and parts are scarce. What I still am fuzzy on: 1. I am guessing that the left coax viewed with the power TB on the right is the input and the right coax is the output. Correct? 2. The power control is derived from a control voltage on the CTRL pin at the right edge. What is the voltage and current requirements? I get that connecting this up to the operating voltage turns it full on, but it looks like it may be the power for the initial driver stage by the way it is connected internally. Hence the question on the current requirement. I don't have a schematic. So my assumption could be way off. Correct me if I am wrong. 4. The M+ and M- pins. I assume this is for metering? If so, is it for current draw or output power? What type of meter would be appropriate? A generic one with x mA FS to read XX? 5. Explain the rationale for the advantages of operating it at reduced voltage. 6. What is the square connector at the upper right corner used for? 7. What is the total current draw when operating at max output for sizing my supply? Thanks, Michael Dinger W9PXZ
