Description

Technical Field

[0001] This invention relates to the field of transceiver component technology, and more specifically, to a reconfigurable transceiver component and its operating method. Background Technology

[0002] In existing transceiver systems, the following methods are typically used to achieve good transmission and reception isolation, avoid noise interference from high-power transmitting circuits on the receiving circuit, and improve the system's receiving sensitivity.

[0003] Method 1: Connect a high-power switch to the output of the transmitting circuit. During system transmission, the high-power switch activates the transmitting circuit, turning it on and the receiving circuit off. The drawback is that the transmitting and receiving circuits cannot operate simultaneously.

[0004] Method 2: Connect a high-power circulator to the output of the transmitter. During system transmission, the transmitting circuit is powered on, and the receiving circuit is powered off. During reception, the transmitting circuit is powered off, and the receiving circuit is powered on. This method allows switching between the transmitting and receiving circuits. The disadvantage is that it cannot achieve simultaneous operation of the transmitting and receiving circuits.

[0005] Method 3: Physically separate the transmitting and receiving circuits in the system, designing them as two independent components. Although this improves the spatial isolation between the transmitting and receiving circuits, the high noise during transmission still prevents simultaneous transmitting and receiving. Furthermore, designing the transmitting and receiving circuits as two separate components further increases the complexity of the system.

[0006] Method 4: Connecting a high-power duplexer to the output of the transmitting circuit allows for simultaneous transmission and reception. The disadvantage is that the high-power duplexer has a cavity structure, resulting in large size and weight, making system integration difficult. This limits its large-scale application in space-constrained environments such as airborne and aerospace systems.

[0007] Of the transceiver component technologies mentioned above, the first three methods are inadequate in that they cannot achieve simultaneous transmission and reception. The fourth method, while capable of simultaneous transmission and reception, results in a large and heavy high-power duplexer, making it unsuitable for use in confined spaces. Summary of the Invention

[0008] The present invention aims to provide a reconfigurable transceiver component and its operating method, so as to enable the receiving circuit and transmitting circuit of the transceiver component to work simultaneously by selecting a low-power filter network and a high-power filter network, thereby improving the flexibility of system design.

[0009] The present invention provides a reconfigurable transceiver component, including a transmitting circuit, a receiving circuit, a first circulator, and a second circulator;

[0010] The transmitting circuit includes a first single-pole double-throw switch, a second single-pole double-throw switch and a third single-pole double-throw switch, a first low-power bandpass dielectric filter and a second low-power bandpass dielectric filter, a first bridge and a second bridge, a first ultra-wideband amplifier and a second ultra-wideband amplifier, and a first high-power bandpass dielectric filter and a second high-power bandpass dielectric filter.

[0013] In each receiving circuit, the input terminal of the fourth single-pole double-throw switch is connected to either the first or second circulator. Of the two output terminals of the fourth single-pole double-throw switch, one output terminal is connected to one input terminal of the fifth single-pole double-throw switch via a third low-power bandpass filter and a first broadband LNA, while the other output terminal is connected to the other input terminal of the fifth single-pole double-throw switch via a fourth low-power bandpass filter and a second broadband LNA. The output terminal of the fifth single-pole double-throw switch is connected to the input terminal of the phase-shift attenuation circuit. The output terminal of the phase-shift attenuation circuit is used to output the received signal.

[0014] Furthermore, the method of operating the reconfigurable transceiver component includes:

[0015] By selecting signals from the first, second, third, fourth, and fifth single-pole double-throw switches, signal transmission in different frequency bands and signal reception in different frequency bands can be achieved.

[0016] Furthermore, the implementation of signal transmission and reception at different frequency bands includes:

[0017] Operating mode 1: Enables signal transmission in frequency band 1 and signal reception in frequency band 1;

[0018] Operating mode two: Enables signal transmission in frequency band two and signal reception in frequency band two.

[0019] Furthermore, working mode one specifically includes:

[0020] The transmitted signal is selected by the first single-pole double-throw switch and enters the first low-power bandpass dielectric filter. At this time, the passband is the first transmission band. Then, it passes through the second single-pole double-throw switch and enters the third single-pole double-throw switch.

After being amplified by the first ultra-wideband amplifier, it is output through the A output terminal of the second bridge and then enters the first high-power bandpass dielectric filter. At this time, the reconfigurable transceiver component is set to the first transmission band. The signal then passes through the first circulator and enters the first antenna for external radiation.

[0022] The transmitted signal is selected by the first single-pole double-throw switch and enters the second low-power bandpass dielectric filter. At this time, the passband is the second transmission band. Then, it enters the third single-pole double-throw switch. When the third single-pole double-throw switch selects channel A output, the signal enters the A input terminal of the first bridge. After being amplified by the second ultra-wideband amplifier, it is output through the B output terminal of the second bridge and then enters the second high-power bandpass dielectric filter. At this time, the reconfigurable transceiver component is set to the second transmission band. After passing through the second circulator, it enters the second antenna for external radiation.

[0033] Example

[0034] like Figure 1 As shown, this embodiment proposes a reconfigurable transceiver component, including a transmitting circuit, a receiving circuit, a first circulator, and a second circulator; the receiving circuit includes a first receiving circuit and a second receiving circuit.

[0035] The transmitting circuit includes a first single-pole double-throw switch 11, a second single-pole double-throw switch 14, and a third single-pole double-throw switch 15; a first low-power bandpass dielectric filter 12 and a second low-power bandpass dielectric filter 13; a first bridge 16 and a second bridge 19; a first ultra-wideband amplifier 17 and a second ultra-wideband amplifier 18; and a first high-power bandpass dielectric filter 110 and a second high-power bandpass dielectric filter 111; the first single-pole double-throw switch 11, the second single-pole double-throw switch 14, and the third single-pole double-throw switch 15 are small-signal single-pole double-throw switches.

[0036] The receiving circuit includes a fourth single-pole double-throw switch 21 and a fifth single-pole double-throw switch 26, a third low-power bandpass dielectric filter 22 and a fourth low-power bandpass dielectric filter 23, a first broadband LNA 24 and a second broadband LNA 25, and a phase-shifting attenuation circuit 27.

[0037] The input terminal of the first single-pole double-throw switch 11 is used to input the transmitted signal; the two output terminals of the first single-pole double-throw switch 11 are respectively connected to the two input terminals of the second single-pole double-throw switch 14 via the first low-power bandpass dielectric filter 12 and the second low-power bandpass dielectric filter 13; the output terminal of the second single-pole double-throw switch 14 is connected to the input terminal of the third single-pole double-throw switch 15; the two output terminals of the third single-pole double-throw switch 15 are respectively connected to the two input terminals of the first bridge 16; the two output terminals of the first bridge 16 are respectively connected to the two input terminals of the second bridge 19 via the first ultra-wideband amplifier 17 and the second ultra-wideband amplifier 18; the two output terminals of the second bridge 19 are respectively connected to a receiving circuit and an antenna via the first circulator and the second circulator.

[0038] In each receiving circuit, the input terminal of the fourth single-pole double-throw switch 21 is connected to the first circulator or the second circulator. Of the two output terminals of the fourth single-pole double-throw switch 21, one output terminal is connected to one input terminal of the fifth single-pole double-throw switch 26 via the third low-power bandpass filter 22 and the first broadband LNA 24 in sequence, and the other output terminal is connected to the other input terminal of the fifth single-pole double-throw switch 26 via the fourth low-power bandpass filter 23 and the second broadband LNA 25 in sequence. The output terminal of the fifth single-pole double-throw switch 26 is connected to the input terminal of the phase-shift attenuation circuit 27. The output terminal of the phase-shift attenuation circuit 27 is used to output the received signal.

[0039] In the reconfigurable transceiver component, signal transmission in different transmission frequency bands and signal reception in different reception frequency bands are achieved through signal selection via the first single-pole double-throw switch 11, the second single-pole double-throw switch 14, the third single-pole double-throw switch 15, the fourth single-pole double-throw switch 21, and the fifth single-pole double-throw switch 26. The reconfigurable transceiver component operates in the following two modes:

[0040] Operating Mode 1: The transmitted signal is selected by the first single-pole double-throw switch 11 and enters the first low-power bandpass filter 12. At this time, the passband is the first transmission band. Then, it passes through the second single-pole double-throw switch 14 and enters the third single-pole double-throw switch 15. When the third single-pole double-throw switch 15 selects channel B output, the signal enters the B input terminal of the first bridge 16, is amplified by the first ultra-wideband amplifier 17, and is output through the A output terminal of the second bridge 19. Then, it enters the first high-power bandpass filter 110. At this time, the reconfigurable transceiver component is in the first transmission band, and the signal is radiated outward by the first circulator. The signal received by the second antenna enters the second receiving circuit through the second circulator. Thus, through the signal selection of the single-pole double-throw switch, the operating frequency band of the receiving circuit is switched to the first receiving frequency band. Through the entire link, the reconfigurable transceiver component realizes the transmission of the first transmission band and the reception of the first receiving frequency band.

[0041] Operating Mode 2: The transmitted signal is selected by the first single-pole double-throw switch 11 and enters the second low-power bandpass filter 13. At this point, the passband is the second transmission band. Then, it passes through the second single-pole double-throw switch 14 and enters the third single-pole double-throw switch 15. When the third single-pole double-throw switch 15 selects channel A output, the signal enters the A input terminal of the first bridge 16, is amplified by the second ultra-wideband amplifier 18, and is output through the B output terminal of the second bridge 19. It then enters the second high-power bandpass filter 111, at which point the reconfigurable transceiver component is set to the second transmission band. The signal then passes through the second circulator and enters the second antenna for external radiation. The signal received by the first antenna passes through the first circulator and enters the first receiving circuit. Thus, through the signal selection of the single-pole double-throw switch, the operating frequency band of the receiving circuit switches to the second receiving band. Through the entire link, the reconfigurable transceiver component realizes both the transmission and reception of signals in the second transmission band.

[0042] In particular, since the amplifier used internally in the reconfigurable transceiver component is an ultra-wideband amplifier, only the bandpass dielectric filter needs to be replaced to realize the development of a reconfigurable transceiver component for a new frequency band, which greatly improves the development efficiency of the transceiver component and shortens the research and development process.

[0043] To verify this invention, an L-band reconfigurable transceiver component was designed. By selecting the required filtering network, the reconfigurable transceiver component can operate simultaneously for both transmission and reception, wherein the transmitting circuit output power is greater than 5 watts, the receiving circuit gain is greater than 50 dB, the noise figure is less than 2, and the transmission-reception isolation is greater than 100 dB.

[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
