            Abstract : 
A millimetre-wave broadband spatial power-combining amplifier has been developed, using a compact waveguide-based spatial power dividing/combining network. In the entire Ka-band, the power dividing/combining network achieves symmetrical four-way power dividing/combining at about 0.2 dB and the power-combining amplifier achieves a combining efficiency of about 72 82.
