Abstract

The invention provides a radio frequency transceiving front end, and the front end comprises an antenna, a transmitting end circuit, a receiving end circuit, a radio frequency switch and a blocking capacitor; the radio frequency switch is connected to the transmitting end circuit and the receiving end circuit, the antenna is connected to two ends of the radio frequency switch through the blocking capacitor, the transmitting end circuit is used for amplifying the power of a radio frequency signal to be transmitted, the receiving end circuit is used for reducing the noise interference of the system and amplifying the received radio frequency signal, and the transmitting end circuit and the receiving end circuit are integrated in a package. The radio frequency switch is connected in series with the transmitting end circuit of the radio frequency transceiving front end, and the transmitting end circuit and the receiving end circuit are integrated together, so that the size of the radio frequency transceiving front end is obviously reduced, and the portability and wide applicability of the radio frequency transceiving front end are improved.

Description

technical field [0001] The invention relates to the field of radio frequency transceiver, in particular to a radio frequency transceiver front end. Background technique [0002] Wireless communication has brought great convenience to human communication and control communication. Wireless communication includes various fixed, mobile and portable applications, such as two-way radios, mobile phones, personal digital assistants and wireless networks. Examples of other radio wireless communication include GPS, garage door remotes, wireless mice, etc. In the era of rapid development of wireless communication technology, the miniaturization of communication system is an important research direction. [0003] In the prior art, a high-power TDD radio frequency system uses a combination of a circulator and a switch to implement transceiver isolation and transmit standing wave protection. Because the high-power RF switch is not easy to realize, the RF switch is often placed at the r...
