Abstract

Embodiments of the present invention provide a radio frequency signal transceiving device and an electronic apparatus. The radio frequency signal transceiving device comprises a transceiver, an amplifier unit connected with the transceiver, a first path used for transmitting a first radio frequency signal of a first frequency band and connected with the amplifier unit, a second path used for transmitting a second radio frequency signal of a second frequency band and connected with the amplifier unit, and a third path used for receiving a third radio frequency signal of the first frequency band and a fourth radio frequency signal of the second frequency band and connected with the transceiver. According to the embodiments of the invention, on the premises that the number of radio frequency devices is reduced, the layout space is saved and the requirement of an antenna switch port is lowered, the downlink carrier aggregation is realized.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a radio frequency signal transceiver and electronic equipment. Background technique [0002] With the rapid development of the global Long Term Evolution (LTE, Long Term Evolution) network, more and more countries are developing LTE services. However, due to the large number of LTE frequency bands, the frequency band bandwidth allocated by some operators is relatively narrow, so the carrier aggregation technology ( CA, CarrierAggregation) came into being to integrate scattered spectrum and increase the rate of data services. Among them, CA is mainly divided into two types: inter-band CA and intra-band CA. In inter-band CA mode, different LTE frequency bands need to work at the same time. For example figure 1 The shown multi-mode multi-frequency front-end device, the electronic equipment including the multi-mode multi-frequency front-end device supports the first frequency b...
