内容記述 | A crystal-controlled transmitter has been developed for a telemetry system of a scientific balloon experiment. The transmitter is designed to send 16kHz PCM data or black and white TV camera signals by FM modulation. A carrier frequency of the transmitter is controlled by a PLL circuit and can be adjusted from 1670MHz to 1690MHz. The nominal out-put power is 0.5W and it can be easily increased to 5W by adopting a power booster amplifier. In order to eliminate EMI noise effect, the main unit of the transmitter is contained in a small aluminum case. It also serves as an effectve heat sink. The antenna unit is attached to a frame of a gondola and connected to the main unit through a coaxial cable. The transmitter was applied to 15 balloon flights and all worked well. The frequency drift was smaller than 16kHz nominal under the temperature condition in a stratosphere. The transmitter is expected to become one of the standare instrument for scientific balloon experiments. | |||||
