Abstract
A mixed-signal circuit board can provide a flexible arrangement of multiple RF transmission mediums in a single lightweight and compact structure as well as support embedding electronic devices within RF transmission paths. The transmission mediums may include a voided waveguide, a dielectric waveguide, a microstrip, a suspended microstrip, a traditional stripline, and a suspended stripline. The center conductors in each transmission medium may be constructed on the same plane or the same PCB layer in order to simplify coplanar design. A distribution board can be provided to deliver the power supply and control signals to the active electronic devices placed in the signal path of the RF board for signal processing and within covered cavities provided within the RF board.
