Abstract:
A radio frequency balanced-unbalanced transformer for impedance matching in a circuit containing a ground plane, set transformer comprising:a first, non-closed conductor loop having an input end electrically connected to said ground plane and also having an output end;a second, non-closed conductor loop substantially parallel to said first conductor loop, said second conductor loop having a first end for signal input and a second end, adjacent to the output end of said first conductor loop for signal output;first capacitive means connected between the first end of said second conductor loop and the second end of said conductor loop, said first and second ends of said first conductor loop being disposed in substantially adjacent positions;second capacitive means electrically connected across said first and second conductor loops at a point intermediate said first and second ends and said input and output ends respectively;third capacitive means connecting said output end of said first conductor to said ground plane.
