Abstract

An improved system for simplifying a complex waveguide network in a satellite system is described herein. A waveguide network device may be configured with at least two housing portions attached together. This enables the waveguide network device to receive an arbitrary number of waveguide routes and output the routes in any configuration, effectively simplifying the overall waveguide network architecture.

First claim

What is claimed:

1. A device for directing waveguide routes, the device comprising:
at least two housings attached together, the at least two housings comprising:
a first housing including one or more first housing waveguide channels, wherein each of the one or more first housing waveguide channels includes a first housing input port and a first housing output port; and
a second housing configured to attach to the first housing, wherein the second housing includes one or more second housing waveguide channels, wherein each of the one or more second housing waveguide channels includes a second housing input port and a second housing output port; and

a sheet, disposed between the first housing and the second housing, the sheet being of a thickness less than any dimension of any of the one or more first housing waveguide channels and one or more second housing waveguide channels;
wherein the second housing is configured to receive a signal from the first housing input port of the one or more first housing waveguide channels;
wherein the second housing is configured to redirect the signal to the second housing output port via a first aperture in the sheet or the first housing output port via the first aperture in the sheet and a second aperture in the sheet; and
wherein a number of waveguide channels in the second housing is different than a number of waveguide channels in the first housing.

2. The device of claim 1 , wherein the first housing and the second housing are vacuum brazed together with the sheet disposed therebetween to form the device.

3. The device of claim 1 , wherein the device is located inside of a payload cavity of a satellite system at an antenna-payload interface.

4. The device of claim 1 , wherein the signal includes a radio frequency (RF) signal.

5. The device of claim 1 , wherein the device is configured to be manufactured by a printer.

6. The device of claim 5 , wherein the printer is a three-dimensional (3-D) printer.

7. The device of claim 1 , wherein:
the first housing output port or the second housing output port to which the signal is redirected is predetermined; and
the second housing and the first housing are attached using a double 90 degree bend.

8. A device for directing waveguide routes, the device comprising:
a first housing having one or more first housing waveguide channels and a second housing having one or more second housing waveguide channels;
the device configured to:
receive, from an input port of the one or more first housing waveguide channels in the first housing, a signal;
redirect the signal to a predetermined output port of one of the one or more first housing waveguide channels and the one or more second housing waveguide channels via one or more apertures of a sheet being of a thickness less than any dimension of the one or more first housing waveguide channels and the one or more second housing waveguide channels, wherein:
the first housing and second housing are configured to attach to each other with the sheet disposed therebetween;
a number of the one or more first housing waveguide channels is less than a number of the one or more second housing waveguide channels.

9. The device of claim 8 , wherein the first housing and the second housing are configured to be attached using a double 90 degree bend.

10. The device of claim 8 , wherein the first housing and the second housing are vacuum brazed together to attach and form a single device.

11. The device of claim 10 , wherein the device is located inside of a payload cavity of a satellite system at an antenna-payload interface.

12. The device of claim 8 , wherein the device is further configured to be manufactured by a three-dimensional (3-D) printer.

13. The device of claim 8 , wherein the signal includes a radio frequency (RF) signal.

14. A method comprising:
forming a first housing including one or more first housing waveguide channels, wherein each of the one or more first housing waveguide channels in the first housing includes a first input port and a first output port,
forming a second housing including one or more second housing waveguide channels, wherein each of the one or more second housing waveguide channels in the second housing includes a second input port and a second output port; and
determining a device output port for a signal from the one or more first output ports or the one or more second output ports; and
in response to the determination, attaching the first housing to the second housing with a sheet disposed therebetween to form a single device;
wherein the single device is configured to redirect the signal to the determined device output port via one or more apertures of the sheet;
wherein the sheet is of a thickness less than any dimension of any of the one or more waveguide channels of the first housing and the second housing; and
wherein a number of first housing waveguide channels is different than a number of second channel waveguide channels.

15. The method of claim 14 , wherein the first housing and the second housing are formed using a three-dimensional (3D) printer.

16. The method of claim 14 , wherein the signal includes a radio frequency (RF) signal.

17. The method of claim 14 , wherein attaching the first housing and the second housing includes vacuum brazing together the first housing and the second housing to form the single device.

18. The method of claim 14 , wherein the single device is located inside of a payload cavity of a satellite system at an antenna-payload interface.

19. The method of claim 14 , further comprising installing the single device in a satellite.

20. The method of claim 14 , wherein the second housing and the first housing are attached using a double 90 degree bend.
