Planar Disk Power Divider for Amplifier Characterization at C-Band

A low loss sectorial disk microstrip power divider is developed and employed for characterization of on-board amplifier. Standard topologies employ 4-port directional couplers attached together so as to simultaneously test various parameters such as frequency, power and modulation index for the on-board operations. In case of low power applications simple sectorial disk planar power divider can measure these parameters. The realized divider is totally planar and integrated with multiple measurement equipment for the amplifier characterization. The measured results of the developed power divider show close analogy with the simulated values. The proposed topology is further integrated with the amplifier test bench set-up at C-band for the complete characterization and results are validated with the typical measurement using the standard topology.
