Receiver for receiving RF-signals in a plurality of different communication bands and transceiver

摘要

A receiver for receiving RF-signals in a plurality of different communication bands, each communication band including a receive frequency range and a transmit frequency range includes a plurality of receiving ports, a plurality of input circuits, a first inductor and a second inductor. Each receiving port is configured to receive RF-signals in a receive frequency range of a communication band. Each input circuit is connected to an associated receiving port for processing RF-signals applied to the receiving port. The first inductor is connected to a first group of input circuits and the second inductor is connected to a second group of input circuits, wherein the first group of input circuits and the second group of input circuits are disjunct. The receiving ports associated with the first group of input circuits are configured to receive RF-signals in a first group of communication bands, wherein in the first group of communication bands, none of the transmit frequency ranges overlap with one of the receive frequency ranges. The receiving ports associated with the second group of input circuits are configured to receive RF-signals in a second group of communication bands, wherein in the second group of communication bands, none of the transmit frequency ranges overlaps with one of the receive frequency ranges.
