TH-3 Microwave Radio System: Power System

One design goal for the T H - 3 radio system was to use or adapt, as much as possible, existing T D - 3 powering arrangements. A number of power-related T D - 3 facilities, requiring little or no change for T H - 3 use, included the -- 19-volt regulator, the common --24-volt battery plant, and dc distribution and radio-building grounding arrangements. These items will not be discussed here, as they have been detailed in an earlier paper. 1 On the other hand, the 6-GHz, ten-watt, RF outputpower objective for T H - 3 required a new TWT, coded the 464A,2 and an associated T W T power supply.
