Abstract

Broadband power divider operating over the frequency band assigned for all domestic mobile communications is designed and implemented. The implemented power divider with 20Watts power rating has the maximum insertion loss of 3.49dB, input reflection coefficient of below -18.48dB and output reflection coefficient of below -20.2dB, above 24.7dB isolation and -141.2dBc of 3rd PIMD over the operating frequency of 810 ~ 2620MHz.

국내 이동통신 주파수를 모두 수용할 수 있는 광대역분배기를 설계 및 제작하였다. 제작한 20W급 광대역분배기는 810 ~ 2620MHz의 동작주파수에서 삽입손실은 최대 3.49dB, -18.48dB 이하의 입력반사계수, -20.2dB 이하의 출력반사계수, 24.7dB 이상의 격리도 그리고 3차 PIMD(Passive Intermodulation Distortion)는 -141.2dBc의 성능을 갖는다.
