Abstract

A radio frequency circuit switch chip, which can transmit and receive high-frequency signals, intermediate-frequency signals or low-frequency signals, or transmit and receive carrier aggregation signals of high-frequency signals and low-frequency signals, or transmit and receive intermediate-frequency signals through different on-states of the first switch and the second switch. Carrier aggregation signal with low frequency signal. The invention also provides a radio frequency circuit, an antenna device and electronic equipment.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a radio frequency circuit switch chip, a radio frequency circuit, an antenna device and electronic equipment. Background technique [0002] With the development of communication technologies, mobile terminals can support more and more communication frequency bands. For example, an LTE (Long Term Evolution, long term evolution) communication signal may include a signal with a frequency between 700 MHz and 2700 MHz. [0003] The radio frequency signals that the mobile terminal can support can be classified into low frequency signals, intermediate frequency signals and high frequency signals. Wherein, each of the low-frequency signal, the intermediate-frequency signal and the high-frequency signal includes a plurality of sub-frequency band signals. Each sub-band signal needs to be transmitted to the outside world through an antenna. [0004] Thus, a carrier aggregation (Car...
