Description

. Изобретение относится к технике СВЧ и может найти широкое применение в системах АФ АР, передающих устройствах и системах, использующих мощность СВЧ.. The invention relates to microwave technology and can be widely used in AF AR systems, transmission devices and systems using microwave power.

Целью изобретения является увеличение рабочей мощности.The aim of the invention is to increase operating power.

На фиг. 1 представлена принципиальная схема делителя мощности; на фиг. 2 пример топологии делителя мощности на два. .. . . ' 'In FIG. 1 is a schematic diagram of a power divider; in FIG. 2 is an example of the topology of a power divider into two. .. . ''

Делитель мощности, содержит входное . плечо, подсоединенное к четвертьволновым отрезкам линии передачи 2, к другому концу которых присоединены отрезки линий с потерями 3 и нагрузки 4. Отрезки линий с потерями 3 соединены в звезду.. К общей точке отрезков линий с потерями 3 подклю* чен шлейф 5, короткозамкнутый на конце.Power divider, contains input. a shoulder connected to quarter-wave segments of transmission line 2, to the other end of which segments of lines with losses 3 and loads 4 are connected. Line segments with losses 3 are connected to a star. A loop 5 is connected to the common point of the segments of lines with losses 3, short-circuited to the end.

Claims

Claim

A power divider comprising an input arm connected via quarter-wave lengths of the transmission line to the output arms, ballast resistors connected to the star and connected to a common point connected to a common loop, short-circuited at the end, connected to the common point with that one. what; In order to increase the operating power, the ballast resistors are made Βι as lossy line segments, the loop length Im is selected to be less than a quarter of the wavelength, and its input resistance X is selected from the relations

IX + Zcthy ^ ^C Zc + IXthy ^

X = Zmtg ~ rlui:

where Zc, L is the impedance and the length of the line segment with losses, respectively;

y is the propagation constant in the line with losses;

Z _m - wave impedance of the loop;

Λ is the wavelength.
