A coaxial-conical-radial transmission line conversion circuits have been investigated to realize a low loss high performance microwave power divider/combiner. In order to optimize the characteristics of the device, the power divider/combiner was designed separately with two parts-the inner part and the outer part. Utilizing the rectangular approximation of the outer part, we can design the low loss device which is not affected by the partition number N of the outer part. The small return loss which is lower than 20㏈ was obtained on the frequency range of 5.15㎓(7.45~12.60㎓). A conical connector was employed for smooth connection between the central coaxial line and the outer radial line. Making use of the 47° and 90° 2-stage conical connector, the return loss lower than 30㏈ was obtained on the operating frequency range of 5㎓. The total return loss of the designed divider/combiner was lower than 20㏈ on the frequency range of 5㎓ for the partition number N=11, N=12 and N=16.
