Abstract
A novel design of quad-band power divider (PD) is proposed in this brief. By introducing the stepped impedance coupled lines, the frequency offset and power loss caused by dispersion are effectively reduced. This brief gives the complete theoretical derivation and design flow of the proposed quad-band PD, according to which people can design the PD operating in four bands. Finally, according to the design method, a quad-band PD operating at 0.7, 2.4, 3.6 and 5.3 GHz is simulated and designed. After processing and measurement, it exhibits low return loss and high isolation in the four operating bandwidths, and the simulation results are highly consistent with the experimental results, which proves the correctness of the proposed design method.
