an rf interface

Abstract

The invention relates to an RF (radio frequency) interface. The RF interface comprises a radio frequency transceiving unit, a storage unit, a CPU (central processing unit) unit, an external control interface and an input / output unit, wherein the radio frequency transceiving unit comprises a radio frequency data interface and a radio frequency control interface; the radio frequency control interface is connected with the CPU unit; the CPU unit controls the radio frequency transceiving unit; the CPU unit is connected with the input / output unit; the CPU unit controls the input / output unit; and the CPU unit is connected with the external control interface; the external control interface transmits an external control command to the CPU unit; the radio frequency data interface is connected with the input / output unit; and the input / output unit is connected with the storage unit. The RF interface has the advantages as follows: the circuit structure can be changed according to different modulation and demodulation needs, without redesign and production of a circuit; and in a quick-in and quick-out data access way, the RF interface effectively avoids data loss.

Description

technical field [0001] The invention relates to a high-frequency radio wave transceiver, especially a radio frequency (RF) interface. Background technique [0002] The known RF interface usually includes a radio frequency transceiver module and an external data interface, the data to be sent is transmitted to the radio frequency transceiver module by the external data interface for transmission, and the received data is transmitted to the external data interface by the radio frequency transceiver module, this form The RF interface often causes data loss due to the speed matching problem between the radio frequency transceiver module and the external data interface. As an improved form, the buffer device is set between the radio frequency transceiver module and the external data interface. Although this form can be improved to a certain extent Data is lost, but digital modulation and demodulation of data cannot be realized to meet the needs of digital communication. Although ...

[0002] The known RF interface usually includes a radio frequency transceiver module and an external data interface, the data to be sent is transmitted to the radio frequency transceiver module by the external data interface for transmission, and the received data is transmitted to the external data interface by the radio frequency transceiver module, this form The RF interface often causes data loss due to the speed matching problem between the radio frequency transceiver module and the external data interface. As an improved form, the buffer device is set between the radio frequency transceiver module and the external data interface. Although this form can be improved to a certain extent Data is lost, but digital modulation and demodulation of data cannot be realized to meet the needs of digital communication. Although there are products with added digital modulation and demodulation modules, these products have single functions and can only be used for a specific modulation and demodulation. Once the mode of modulation and demodulation needs to be changed, the circuit design must be changed, which has poor versatility, and it is difficult to avoid data loss when the data traffic is large.
