[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0024] Figure 1 It is an exemplary schematic diagram of an ultra-wideband signal transceiver device provided by some embodiments of the present invention. As Figure 1 shown, the ultra-wideband signal transceiver device provided by the present invention includes an information device, an SDR transceiver module, a signal source, a gating preprocessing module, a broadband microsystem, and a transceiver antenna.

[0025] The information device is used to simulate communication modes and the corresponding analog communication parameters, and communicate with the SDR transceiver module, the signal source, and the broadband microsystem.

[0026] The simulated communication modes may include application modes such as satellite communication, telemetry and telecontrol, and spectrum monitoring. The information devices may include all-in-one machines, keyboards, displays, and AC / DC power supplies, etc. The information devices may send the analog communication parameters to the SDR transceiver module to form baseband signals. For example, the information device integrates an industrial control computer, on which application software runs. The communication modes and various communication parameters to be simulated are configured on the application software and transmitted to the SDR (software defined radio) circuit inside the SDR transceiver module to form baseband signals.

[0027] In some embodiments, the information device includes a USB port and an RS422 port for external communication and a LAN port for communication with the SDR transceiver module.

[0028] In some embodiments, the analog communication parameters include code rate, modulation mode, frequency value, and type of transmitted information.

[0029] The SDR transceiver module is used to shift the baseband signal to the first carrier frequency band, perform signal acquisition, signal generation, and digital preprocessing, and communicate with a signal source, a gating preprocessing module, and a broadband microsystem.

[0030] The frequency band range of the first carrier frequency band is 70 MHz to 6 GHz. Based on the SDR transceiver module, functions such as modulation and demodulation of signals from 70 MHz to 33 GHz are designed and implemented. Through flexible configuration, application modes such as satellite communication, telemetry and telecontrol, and spectrum monitoring can be simulated.

[0031] In some embodiments, the SDR transceiver module includes a LAN port for communication with the information device, IF-T and IF-R ports for communication with the gating preprocessing module, a CTRl port for communication with the broadband microsystem, and an SPI port for communication with the signal source. The SDR transceiver module is used to convert the baseband signal into an intermediate frequency output signal; the SDR transceiver module is also used to demodulate the preprocessed intermediate frequency input signal transmitted by the gating preprocessing module and the variable intermediate frequency input signal transmitted by the broadband microsystem to obtain the information configured by the ground application software.

[0032] The signal source is used to generate an oscillation signal, transmit the oscillation signal to the SDR transceiver module, and communicate with the broadband microsystem.

[0033] The gating preprocessing module is used to gate the signals in the first carrier frequency band and communicate with the broadband microsystem and the transceiver antenna.

[0034] In some embodiments, the frequency band range of the signals gated by the gating preprocessing module is 70 MHz to 6 GHz.

[0035] The gating preprocessing module is used to gate the intermediate-frequency output signal to obtain a preprocessed intermediate-frequency output signal and send the preprocessed intermediate-frequency output signal to the transceiver antenna; the gating preprocessing module is also used to gate the intermediate-frequency input signal to obtain a preprocessed intermediate-frequency input signal and send the preprocessed intermediate-frequency input signal to the SDR transceiver module. For example, a fixed-frequency analog intermediate-frequency signal with an output frequency range of 70 MHz to 6 GHz after frequency conversion by the SDR transceiver module is transmitted by the transmitting antenna after passing through the gating preprocessing module. During reception, the 70 MHz to 6 GHz signal is directly received by the gating preprocessing module and then demodulated by the SDR circuit of the SDR transceiver module to obtain the information configured by the ground application software.

[0036] The broadband microsystem is used to realize the transceiver conversion of signals between the first carrier frequency band and the second frequency band and communicate with the transceiver antenna; the second frequency band is higher than the first carrier frequency band.

[0037] In some embodiments, the frequency band range of the first carrier frequency band is 70 MHz to 6 GHz; the frequency band range of the second frequency band is 6 GHz to 33 GHz. Therefore, the broadband microsystem can realize the transceiver conversion between the carrier frequencies of 70 MHz to 6 GHz and 6 GHz to 33 GHz, thus avoiding the problems of a large number of functional channels and simple stacking in the prior art. The broadband microsystem has a built-in local oscillator circuit inside and only needs an external highly stable reference signal to realize frequency translation, and can conveniently realize the frequency response of the corresponding functions.

[0038] In some embodiments, the broadband microsystem includes an IF-R port and an IF-T port communicating with the gating preprocessing module, a CTRL port communicating with the SDR transceiver module, a REF port communicating with the signal source, and an RX port and a TX port communicating with the transceiver antenna. For example, the broadband microsystem is used to convert the intermediate-frequency output signal into a high-frequency output signal and send the high-frequency output signal to the transceiver antenna; the broadband microsystem is also used to convert the high-frequency input signal into a variable intermediate-frequency input signal and transmit the variable intermediate-frequency input signal to the SDR transceiver module. Exemplarily, a fixed-frequency analog intermediate-frequency signal with an output frequency range of 70 MHz to 6 GHz after passing through the SDR transceiver module is then shifted by the broadband microsystem to a radio frequency signal in the specified functional frequency band (6 GHz to 33 GHz), and finally the relevant instructions are sent to the terminal command console through the broadband antenna. During reception, after receiving a 6 GHz to 33 GHz signal through the receiving antenna, it is first down-converted by the broadband microsystem to obtain a fixed intermediate-frequency signal, and then demodulated by the SDR circuit of the SDR transceiver module to obtain the information configured by the ground application software.

[0039] The transceiver antenna is used to transmit and receive signals. For example, the transceiver antenna is used to transmit the output signal or receive the input signal.
