Abstract
A device includes a switching unit including N input ports and M output ports, wherein N≧M≧2. The switching unit is configured to selectively interconnect each of the M output ports with a different one of the N input ports. The device further includes M attenuators, wherein each of the M attenuators is electrically coupled to a different one of the M output ports of the switching unit.
Claims20
A device, comprising:
- a switching unit comprising N input ports and M output ports, wherein N≧M≧2, wherein the switching unit is configured to selectively interconnect each of the M output ports with a different one of the N input ports;
- and
- M attenuators, wherein each of the M attenuators is electrically coupled to a different one of the M output ports of the switching unit.
A device, comprising:
- a single-pole double-throw switch comprising a first input port, a second input port and an output port;
- a diplexer comprising an input port, a first output port and a second output port, wherein the input port of the diplexer is electrically coupled to the output port of the single-pole double-throw switch;
- a first attenuator electrically coupled to the first output port of the diplexer;
- and
- a second attenuator electrically coupled to the second output port of the diplexer.
2 more elements
A device, comprising:
- at least two directional couplers, wherein each of the directional couplers is configured to be arranged in an uplink transmission path of an RF front end;
- and
- an M-pole N-throw switch comprising N input ports and M output ports, wherein N≧M≧2, wherein each of the N input ports is electrically coupled to a coupled port of a directional coupler or an isolated port of a directional coupler.
