TV-37 VHF AND TU-11 UHF 2000-WATT TRANSMITTERS.
Abstract
The design, fabrication, and testing of TV-37 and TU-11 Transmitters are discussed. The TV-37 develops 2000 watts of carrier power, is amplitude modulated, and is in the 118- to 136-megahertz band. The TU-11 develops 1500 watts of carrier power, is also amplitude modulated, and is in the 278- to 328-megahertz band. Both transmitter types use essentially the same unit with only minor changes necessary to convert from one to the other. The FAA 50-watt transmitter, type TV-36 or TU-9, is used to drive one linear class AB sub 1 stage in the TV-37 or TU-11 respectively. Safety features protect service personnel. Silicon solid-state components, where possible, along with conservative design ensure reliable operation. Interlocks and monitoring circuits reduce the chance of transmitter damage due to component failure or operator error. One set of equipment was developed to provide angle modulation for the TV-36. Considerable design and development was necessary to ensure proper cooling and electrical stability of the final amplifier stage. Extensive and inclusive testing has shown that the final design meets or exceeds all major development objectives. (Author)
