Claim Text:
1. A compact microstrip to waveguide dual coupler transition, comprising: a multilayer printed circuit board configured with a rectangular region on an upper surface of the multilayer printed circuit board, wherein the rectangular region has a pair of long edges and a pair of short edges; a transition probe configured on the upper surface of the multilayer printed circuit board, wherein a terminal of the transition probe extends into the rectangular region through a long edge of the rectangular region, and another terminal of the transition probe is electrically connected to a power amplifier; a first coupler probe configured on the upper surface of the multilayer printed circuit board, wherein a terminal of the first coupler probe extends into the rectangular region; and a second coupler probe configured on the upper surface of the multilayer printed circuit board, wherein a terminal of the second coupler probe extends into the rectangular region, wherein: the first coupler probe extends into the rectangular region through the same long edge of the rectangular region as the transition probe, and disposed at one side of the transition probe; and the second coupler probe extends into the rectangular region through the same long edge of the rectangular region as the transition probe, and disposed at another side of the transition probe.
