[0002] A ceramic resonator is an electronic component that utilizes the resonant properties of piezoelectric ceramic materials to generate mechanical vibrations by applying an alternating electric field, thereby stably outputting a specific frequency signal. This component covers functions such as frequency control, signal filtering, and clock generation, and can effectively improve the timing accuracy and signal stability of electronic equipment. With the rapid development of technologies such as 5G communications and the Internet of Things, electronic systems have placed higher requirements on the frequency band coverage, port isolation, and temperature stability of resonators. Therefore, in order to meet the electronic system's needs for high performance, high integration, and high reliability, the development of highly integrated multi-frequency, multi-port ceramic resonators is particularly critical.

The spectrum characteristics refer to the distribution characteristics of the crosstalk signal in the frequency domain, including the center frequency, bandwidth, amplitude, etc. The test frequency band refers to the dielectric parameter test frequency range determined according to the spectrum characteristics.

[0032] Optionally, the crosstalk signal of the ceramic resonator can be identified by a vector network analyzer, and based on the spectrum characteristics, the test frequency band of the dielectric parameters of the dielectric layer can be selected using a wide-band dielectric spectrometer. Using the multi-port impedance frequency-varying data, the propagation path and coupling node of the crosstalk signal can be located by infrared thermal imaging, and based on the multi-port impedance characteristics, the impedance matching requirements of the ceramic resonator can be determined using a λ / 4 impedance converter.

[0033] The port isolation module 102 is used to collect electric field simulation data of the ceramic resonator, construct an electric field distribution diagram of the ceramic resonator based on the electric field simulation data, and set a multi-port isolation unit of the ceramic resonator based on the electric field distribution diagram and the multi-frequency test data.

[0035] Furthermore, the embodiment of the present invention constructs an electric field distribution diagram of the ceramic resonator based on the electric field simulation data, thereby identifying the coupling of the electric field between different ports and optimizing the port layout. The electric field distribution diagram refers to a visual chart generated based on the electric field simulation data that describes the distribution of the electric field strength, direction, etc. inside and around the ceramic resonator.

[0040] The embodiment of the present invention can significantly improve the port isolation of the multi-frequency multi-port ceramic resonator by setting a multi-port isolation unit of the ceramic resonator based on the electric field distribution diagram and the multi-frequency test data. The multi-port isolation unit refers to a physical structure or circuit unit designed to reduce or eliminate signal interference (crosstalk) between different ports.

[0042] See Figure 3As shown, it is a structural diagram of a multi-port isolation unit for realizing the multi-frequency multi-port ceramic resonator processing system provided by one embodiment of the present invention. The diagram clearly shows that it can utilize electric field distribution and multi-frequency data to optimize the isolation performance between multiple ports (such as field intensity gradient adaptation and multi-port coupling regulation) by showing the multi-port layout and internal resonance and isolation structure. Compared with the single transmission path of a single product and a single port, it highlights the design logic of collaborative isolation, compensation and multi-band threshold adaptation of multiple ports in complex frequency bands, which helps to understand the special structural advantages of the multi-port isolation unit for multi-signal interaction scenarios.

[0043] Among them, the field intensity gradient data refers to the rate of change data of the electric field intensity inside the ceramic resonator with spatial position. For example, at the edge of the electrode or the port connection, the field intensity may change dramatically, and the field intensity gradient data is large; while inside the ceramic medium far away from the port, the field intensity changes relatively slowly, and the gradient data is small. The S parameter matrix refers to the scattering parameter matrix that characterizes the frequency domain signal transmission and reflection characteristics between multiple ports of the ceramic resonator. For example, for a ceramic resonator with n ports, its S parameter matrix is ​​a (nxn) complex matrix. The port coupling coefficient refers to the parameter that quantifies the energy coupling strength between ports. For example, the coupling coefficient from port 1 to port 2 is 0.1 (or -20dB), which means that 10% of the signal input from port 1 is coupled to port 2. The optimal The isolation structure parameters refer to the geometric parameters of the isolation wall required to reduce the coupling coefficient to the target value, including but not limited to the thickness, material, and position of the isolation wall, and the shape, size, and material of the shielding layer. The phase information refers to the phase angle component in the S parameter. The adaptive isolation compensation scheme table refers to a set of isolation compensation schemes for different frequencies and different working states generated by using the phase information of multi-frequency test data and combining the requirements of the ceramic resonator under different working conditions. For example, within a specific frequency range, when it is detected that the phase difference between ports causes increased crosstalk, the scheme table will provide compensation measures such as adjusting the capacitance value in the matching network, changing the grounding method of the shielding layer, or enabling specific filters.
