Wireless communication systems and terminal equipment

Abstract

The design refers to wireless communication systems, methods, equipment, and chips. Frequency band selection circuitry is arranged. The selector circuit can separately route the first and second radio frequency signals to the first, second, or third near-end circuits, and the first, second, or third near-end circuits can perform filtering and / or combining on the first and second radio frequency signals. In this configuration, the first near-end radio frequency channel is configured to transmit the first radio frequency signal, and the second near-end radio frequency channel is configured to transmit the second radio frequency signal. These channels can share the filter circuit, so that devices such as filters and multiplexers at the near-end radio frequency can be reduced, thereby reducing the space occupied by the near-end radio frequency module.
