Abstract:
1. An RF transformer comprising: first and second dielectric plates each having a first surface and a second surface, the first and second dielectric plates having the first surfaces thereof bonded together by a dielectric adhesive material; a first transformer winding in the form of a first electrically conductive strip disposed between the first surface of the first dielectric plate and the first surface of the second dielectric plate, wherein the first transformer winding serves as one of either a primary winding or a secondary winding, a second transformer winding in the form of a second electrically conductive strip formed on the second surface of the first dielectric plate, said second transformer winding being positioned to at least partially overlie the first transformer winding, and a ground plane electrode formed on the second surface of the second dielectric plate; and an electrical connector connecting the second transformer winding to the ground plane electrode via a via-hole that extends through the first and second dielectric plates.
