Embodiment Construction
[0065] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:
[0066] In this embodiment, an arbitrary positive real number C with a unit of Ω is introduced, and the figure 1 The external load resistance in the change into R 2 = K 2 ×C and R 3 =C. And if image 3 As shown in , the length of the two sections is a quarter wavelength, and the characteristic impedance is Z 4 and Z 5 The transmission line is used to connect R 2 and R 3 Transform to Z 0 (50Ω).
[0067] It can be seen from the background knowledge that the design of the unequal power divider must meet the following two conditions: the output power of port 3 is the K of port 2 2 The voltage between port 2 and port 3 is equal to the ground respectively, so the characteristic impedance of all transmission line segments in port 2 must be K of the characteristic impedance of the transmission line segment corresponding to port 3 2 times. And using the matchin...
