Multi-band radio frequency front-end device, multi-band receiver, and multi-band transmitter

A multi-band receiver, comprising:

• a first receive channel, configured to process a signal on a band n260;
• and
• a second receive channel, configured to process a signal on at least one band in n257, n258, or n261;
• wherein the first receive channel comprises a first matching network and a radio frequency front-end circuit operable on the band n260 and connected to the first matching network, and wherein the first matching network supports the band n260;
• wherein the second receive channel comprises a second matching network, and the second matching network supports a band in n257, n258, and n261;
• and
• wherein routing of the first matching network and routing of the second matching network within a layout are annular and nested.

A multi-band transmitter, comprising:

• a first transmit channel, configured to process a signal on a band n260;
• and
• a second transmit channel, configured to process a signal on at least one band in n257, n258, or n261;
• wherein the first transmit channel comprises a first matching network and a radio frequency front-end circuit connected to the first matching network, and wherein the first matching network supports the band n260;
• wherein the second transmit channel comprises a second matching network, and wherein the second matching network supports a band in n257, n258, and n261;
• and
• wherein routing of the first matching network and routing of the second matching network on a layout are annular and nested.
