Abstract

The invention provides a radio frequency system and communication equipment. The system comprises a radio frequency transceiver, a first receiving and transmitting module, a receiving module, a firstMIMO receiving module, a second MIMO receiving module, a first antenna, a second antenna, a third antenna, and a fourth antenna. The radio frequency transceiver is connected with the first antenna through the first transceiver module to form a first MIMO receiving channel of 5G signals, and is connected with a second antenna through a receiving module to form a second MIMO receiving channel of 5Gsignals; the radio frequency transceiver is connected with the third antenna through the first MIMO receiving module to form a third MIMO receiving channel of 5G signals, and is connected with the fourth antenna through the second MIMO receiving module to form a fourth MIMO receiving channel of 5G signals. The radio frequency system can support the 4 * 4 MIMO function of 5G signals of four presetfrequency bands, the use efficiency of the first MIMO receiving module and the second MIMO receiving module is improved, the cost is reduced, the space occupied by the device can be reduced, and the link loss of a receiving path can be reduced at the same time.

Description

technical field [0001] The present application relates to the field of radio frequency technology, in particular to a radio frequency system and communication equipment. Background technique [0002] With the development and progress of technology, in order to meet the increasing demands of various network standards and at the same time solve the problem of tight PCB layout, the high integration and miniaturization of devices has become a development trend. From Phase 2 products that only support single-band at the beginning, to Phase 7 products that support the integration of various standards, the integration level of devices is getting higher and higher, and the package size of devices is getting smaller and smaller. When this Phase7 product, for example, a diversity receiving device used to support the medium and high frequency bands of LTE signals is applied to a radio frequency transceiver system to support the MIMO function of 5G NR signals, the cost is high and the s...
