Abstract
Various embodiments implement waveguides for signal distribution or signal filtering in satellite receivers. According to some embodiments, a low noise block downconverter (LNB) is implemented using waveguides configured for signal distribution, band pass filtering, low pass filtering, high pass filtering, or band stop filtering. For some embodiments, the waveguides may be formed by the LNB chassis and the ground plane of a printed circuit board mounted to the LNB chassis.
Claims21
An apparatus, comprising:
- a chassis;
- a printed circuit board comprising a ground plane and a device layer;
- a first device disposed on the device layer;
- a second device disposed on the device layer;
- and
- a waveguide coupling the first device and the second device, the waveguide having at least one side formed by a groove in the chassis and at least one side formed by the ground plane of the printed circuit board.

A method, comprising:
- receiving a first signal at a first device disposed on a device layer of a printed circuit board, wherein the printed circuit board comprises a ground plane and the device layer;
- transmitting a second signal, from the first device to a second device disposed on the device layer of the printed circuit board, using a waveguide having at least one side formed by a groove in a chassis housing the printed circuit board and at least one side formed by the ground plane of the printed circuit board, wherein the second signal is based on the first signal;
- and
- receiving the second signal at the second device disposed on the device layer of the printed circuit board.
