Radio frequency DRX device, radio frequency transmit-receive system and communication device

Abstract

The invention provides a radio frequency DRX device, a radio frequency transmit-receive system and a communication device, the radio frequency DRX device is configured with a low frequency receiving port, a plurality of medium and high frequency receiving ports and a plurality of antenna ports, and the radio frequency DRX device comprises a first receiving circuit used for performing filter amplifier processing on a received low frequency signal, the low-frequency signal of any frequency band is selectively output to the low-frequency receiving port; the first switch unit is used for selectively conducting a receiving path of any low-frequency signal; the second receiving circuit is used for carrying out filter amplifier processing on the received medium-high frequency signals so as to selectively output medium-high frequency signals of multiple frequency bands to multiple corresponding medium-high frequency receiving ports; and the second switch unit is used for selectively conducting at least one medium-high frequency signal receiving path so as to reduce cascade noise coefficients of the low-frequency signal receiving path and the medium-high frequency signal receiving path, so that the sensitivity of the radio frequency DRX device, the radio frequency transceiving system and the communication equipment can be improved.

Description

technical field [0001] The present application relates to the field of radio frequency technology, in particular to a radio frequency DRX device, a radio frequency transceiver 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. Generally, a receiving module is defined in 2G, 3G or 4G architecture design, but when the module is applied to a radio frequency transceiver system to receive radio frequency signals, the sensitivity of the receiving...

AI Technical Summary

Problems solved by technology

Generally, the receiving module is defined in the architecture design of 2G, 3G or 4G. However, when the module is applied to the RF transceiver system to receive RF signals, the sensitivity of the receiving channel in the RF transceiver system is low.
