- W2356198137 abstract "This paper introduces a type of 2-way combiner of different frequencies based on the theory of transmission line transformer.The combiner makes two input signals of different power and frequencies into one output signal,which can be sent by single shortwave antenna to reduce the quantity and the area of antenna site.We accomplish the method of power combiner of different frequencies based on the theory of the same frequency.It includes two parts: the impedance transtormation and the power combination.The circuit parameter is determined by the requirement of isolation degree,insertion loss,VSWR and the power capcity of the magnetic core.In this paper,we establish the thermal design method of forced air cooling,discuss the design method of the radiator and the air fan by theoretical calculation and computer simulation.The combiner with the dimension of 290mm×194mm×360mm was designed,featuring isolation: ≥30dB,insert loss: ≤0.3dB,VSWR: ≤1.25,properties stability: ≤0.3dB,power capacity: 2×1000W(average) in frequency range of 1.6 to 30MHz." @default.
