I find a paper (please see attached) which describes a 200W power amplifier design.
The paper mentioned it use two-stages matching circuits consists of a quarter wavelength microstrip line impedance-transformer.
But I can not understand the matching network.
Why there is a slot at input port ?
Does it use wilkinson couplers to combine the two device?
Thanks a lot.
