Abstract

The invention belongs to the technical field of communication of the Internet of Things and relates to a wireless transceiver and a control method thereof. The wireless transceiver and the logic control method thereof solve the technical problems that existing design is not reasonable and the like. A crystal oscillator circuit, a Balun circuit, a power processing circuit and a user interface module are connected to an RF communication chip. The user interface module comprises a power interface, an SPI interface, an REN control interface and a TEN control interface. The power interface is connected with the power processing circuit, the SPI interface is connected with the RF communication chip, the REN control interface is connected with a signal processing and switching unit through an RXEN control line, and the TEN control interface is connected with the signal processing and switching unit through a TXEN control line. The power processing circuit and the Balun circuit are respectively connected with the signal processing and switching unit, and an antenna is connected to the signal processing and switching unit. The wireless transceiver and the control method thereof have the advantages that the structure is simple and compact, the number of used modules is small, and cost is low; the transmission power is high, the transmission frequency can be adjusted, and using of the wireless transceiver and the logic control method thereof is flexible and convenient.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things communication, and relates to wireless transmission equipment, in particular to a wireless transceiver and a logic control method thereof. Background technique [0002] A wireless transceiver is a device that receives and sends wireless signals. Today, with the development of electronic information technology, it has become popular in people's daily life. Wireless transceivers are widely used in industries such as the Internet of Things. Traditional wireless transceivers have complex structures, many modules, high prices, and average transmission power, usually only 10mW, which is not suitable for the development trend of the Internet of Things industry. [0003] For this reason, people have carried out long-term exploration, put forward various solutions. For example, a Chinese patent document discloses a wireless transceiver system [Application No.: 200610034228.8], which includes a...
