Multiband repeater architecture

A multiplexer comprising:

• a common port comprising:
• a first first-direction filter configured to pass a first-direction signal of a first band and a first-direction signal of a second band;
• a first second-direction filter configured to pass a second-direction signal of the first band and a second-direction signal of a third band;
• a second first-direction filter configured to pass a first-direction signal of a third band;
• and
• a second second-direction filter configured to pass a second-direction signal of a second band;
• a first separate port comprising:
• a third first-direction filter configured to pass the first-direction signal of the first band and the first-direction signal of the second band;
• a second separate port comprising:
• a third second-direction filter configured to pass the second-direction signal of the first band and the second-direction signal of the third band;
• a third separate port comprising:
• a fourth first-direction filter configured to pass a first-direction signal of the third band;
• and
• a fourth separate port comprising:
• a fourth second-direction filter configured to pass a second-direction signal of the second band.

A repeater comprising:

• a server port;
• a donor port;
• a first uplink (UL) amplification and filtering path coupled between the server port and the donor port, wherein the UL amplification and filtering path is configured to pass a UL signal of a first band and a UL signal of a second band through a first bandpass filter;
• a first downlink (DL) amplification and filtering path coupled between the server port and the donor port, wherein the first DL amplification and filtering path is configured to pass a DL signal of the first band through a second bandpass filter;
• and
• a second DL amplification and filtering path coupled between the server port and the donor port, wherein the second DL amplification and filtering path is configured to pass a DL signal of the second band through a third bandpass filter;
• wherein:
• the UL signal of the second band comprises a first UL subset band that includes a first UL subset bandwidth less than a bandwidth of the UL signal of the second band;
• the DL signal of the second band comprises a first DL subset band that includes a first DL subset bandwidth less than a bandwidth of the DL signal of the second band;
• the UL signal of the third band comprises a second UL subset band that includes a second UL subset bandwidth less than a bandwidth of the UL signal of the third band;
• and
• the DL signal of the third band comprises a second DL subset band that includes a second DL subset bandwidth less than a bandwidth of the DL signal of the third band.

A repeater comprising:

• a server port;
• a donor port;
• a first first-direction amplification and filtering path coupled between the server port and the donor port, wherein the first-direction amplification and filtering path is configured to pass a first-direction signal of a first band and a first-direction signal of a second band through a first bandpass filter;
• a first second-direction amplification and filtering path coupled between the server port and the donor port, wherein the first second-direction amplification and filtering path is configured to pass a second-direction signal of the first band and a second-direction signal of a third band through a second bandpass filter;
• a second first-direction amplification and filtering path coupled between the server port and the donor port, wherein the second first-direction amplification and filtering path is configured to pass a first-direction signal of the third band through a third bandpass filter;
• a second second-direction amplification and filtering path coupled between the server port and the donor port, wherein the second second-direction amplification and filtering path is configured to pass a second-direction signal of the second band through a fourth bandpass filter;
• a third first-direction amplification and filtering path coupled between the server port and the donor port, wherein the third first-direction amplification and filtering path is configured to pass a first-direction signal of a fourth band through a fifth bandpass filter;
• and
• a third second-direction amplification and filtering path coupled between the server port and the donor port, wherein the third second-direction amplification and filtering path is configured to pass a second-direction signal of the fourth band through a sixth bandpass filter.
