Description
Предлагаетс устройство дл поглощени четных гармоник коротковолнового передатчика. Согласно изобретению, к зажимам генератора присоединен шлейф длиной в Я/4, где X -длина волны, на рассто нии АХ/4 от передатчика, где л-любое целое число, каковой шлейф замкнут накоротко мостиком.A device is proposed for absorbing the even harmonics of a short-wave transmitter. According to the invention, a loop of length I / 4, where X is the wavelength, is located at the distance AX / 4 from the transmitter, where is any integer, which loop is short-circuited to the terminals of the generator.
На чертеже изображено схематически -предлагаемое устройство.The drawing shows schematically the proposed device.
К зажимам генератора или к концам катушки / св зи с генератором присоединен шлейф 2, 2 длиной в Х/, где X- длина волны передатчика. Этот шлейф в более обш;ем случае может быть присоединен к фидеру питани антенны на рассто нии дХ/i, как это указано на схеме . Шлейф замыкаетс накоротко мостиком: 3 или соответственно Ji.To the terminals of the generator or to the ends of the coil / connection to the generator, there is connected a train 2, 2 long in X /, where X is the transmitter wavelength. This loop can be connected to the feeder of the antenna at a distance dX / i, as indicated in the diagram. The loop is shorted by a bridge: 3 or Ji, respectively.
Фильтруюш;ее действие устройства «всновано на том обсто тельстве, что эквивалентное сопротивление шлейфа дл основной частоты равно бесконечности, а дл четных гармоник, т.-е. дл волн более коротких, чем основна , в 2п раз, этот шлейф, вл етс коротким замыканием . Включение такого щлейфа в питающий фидер на указанных выше рассто ни х от передатчика должно практически уничтожить все высшие гармоники его.Filtering; its operation of the device is “due to the fact that the equivalent loop resistance for the fundamental frequency is infinity, and for even harmonics, i.e. for waves shorter than the main wavelength, 2 times, this loop is a short circuit. The inclusion of such a plume into the feeder at the above distances from the transmitter should virtually destroy all its higher harmonics.
Предмет изобретени .The subject matter of the invention.
Устройство дл поглощени четных гармоник коротковолнового передатчика, отличающеес тем, что к зажимам генератора присоединен шлейф длиной в Х/, где I.-длина волны, на рассто нии лХ/ от передатчика, где п - любое целое число, каковой шлейф замкнут накоротко мостиком.A device for absorbing even harmonics of a short-wave transmitter, characterized in that a loop of length X is connected to the terminals of the generator, where I. is the wavelength at a distance lX / from the transmitter, where n is any integer number, which is short-circuited.
