High power device of magic-T is adopted with channel power combination technique principle.

The UWB impulse radar target-detection system including a power combination solid state pulse source,a UWB planar horn antenna array for transmitting and receiving,a quadrature demodulation receiver and a computer for controlling is designed,and its theory is presented.

Wide-band power combination is defined and classified in terms of channel and space,and the technical advantages are illuminated from the two aspects.

Presents the relationship of source impedance and load impedance of broadband power combining/splitting networks when the load gains the maximum of power using theory of transmission line and circuit equation The measuring result is accorded with theoretic resul

When connecting the resonant tank to the output port of the transistor in the power combining stage,the impedance matching is more effectively improved in the whole band compared with LC or RLC resonant tanks,hence the gain flatness and the output VSWR are simultaneously improved.

For researching millimeter wave power combining technique,a new style low loss millimeter wave microstrip integrated 3dB hybrid,extracting advantages from traditional Wilkinson hybrid,was proposed.
