| Abstract: | A tunable equal power divider is presented in this paper .This new topology power divider is designed based on complex impedance transformation theory , having three complex impedance transformers , tunable in fre-quency range from 600 MHz to 1 900 MHz, and realizing that the reflection coefficient at the input end S 11 is below-15dB, the transmission coefficient S 21 and S 31 are better than -4 dB.This power divider is compact , and can be biased by simple structure .In addition , harmonics can be suppressed efficiently . |
