We present the design, fabrication and measurement of an in-phase equal power ring divider exhibiting ultra wideband isolation, transmission and port matching. The design uses coplanar techniques to achieve a compact and uniplanar design. The device has been fabricated using a single metal level GaAs monolithic microwave integrated circuit (MMIC) process with electron beam airbridge technology. The device has a dimension of 0.6 mm×0.6 mm including test pads. The measured in-band insertion loss is 1.3 dB and the port match is better than 18 dB over the frequency range from 44 GHz to 110 GHz. The output port-to-port isolation is better than 20 dB over the entire measured frequency range from 10 MHz to 110 GHz. Full-wave simulation results show this performance up to 118 GHz.
