Abstract

The embodiment of the invention provides a radio frequency circuit switch chip, a radio frequency circuit, an antenna apparatus and an electronic device. In the radio frequency circuit switch chip, an input end of a first switch comprises a high frequency port, the input end of a second switch comprises a medium frequency port and the input end of a third switch is a low frequency port; the first switch selectively turns on a combiner through a fourth switch, and meanwhile the third switch turns on the combiner so as to realize carrier aggregation of high frequency signals and low frequency signals; and the second switch can selectively turn on the combiner through the fourth switch, and meanwhile the third switch turns on the combiner so as to realize the carrier aggregation of medium frequency signals and the low frequency signals. In the scheme, the radio frequency circuit switch chip can switch to control the radio frequency signals of different frequency bands to perform the carrier aggregation, thereby reducing the insertion loss of the radio frequency circuit and improving the carrier aggregation flexibility of the radio frequency signals by the electronic device.

Description

technical field [0001] The invention relates to the technical field of mobile 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 continuous development of mobile communication technology, people have higher and higher communication requirements for mobile terminals, and mobile terminals can support more and more communication frequency bands. For example, LTE (Long Term Evolution, Long Term Evolution) communication signals can include frequencies in Signals between 700MHz and 2700MHz. [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 correspondingly includes a plurality of sub-frequency band signals. Each sub-band...
