Abstract :
In this paper, a circular power combiner/divider using coplanar strip-lines operating at the centre frequency of 30 GHz is demonstrated. The combiner/divider has a coplanar strip-line (CPS) crossover phase inverter and it shows good isolation (<;-22 dB) up to 55 GHz. The combiner/divider is suitable for combining planar Gunn oscillators that operate in a wide frequency range.
