For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0030] It should be noted that the frequency source plays a crucial role in electronic systems, mainly responsible for providing stable and accurate frequency signals, which are the basis for the normal operation of the system. The phase noise of the frequency source is crucial to the performance of the system. The frequency source circuit is a very sensitive circuit module, which is easily affected by vibration, temperature shock, mechanical stress, etc. These will cause the short-term phase noise of the frequency source circuit to deteriorate, and the frequency signal cannot provide a stable phase. The voltage-controlled oscillator is the core component of the frequency source circuit. Due to the piezoelectric effect of ceramic materials, when the ceramic material is subjected to mechanical pressure, a voltage will be generated between the two end faces. This voltage modulates the voltage-controlled oscillator, which will cause phase noise deterioration, phase jitter and other problems. Therefore, the embodiment of the utility model provides an anti-vibration device for a microwave frequency source and a microwave transceiver, aiming to solve the problem that the frequency source circuit cannot effectively reduce the vibration received by the frequency source circuit, causing the short-term phase noise of the frequency source circuit to deteriorate, and the frequency signal cannot provide a stable phase.

[0031] Figure 1 The structure diagram of the PCB in the anti-vibration device for a microwave frequency source provided by the embodiment of the utility model is shown in Figure 1 The PCB 110 includes a damping area 111, a connection area 112 and a non-damping area 113.

[0032] The hollow part of the connection area (the shaded part of the connection area 112) can be a strip-shaped groove arranged around the damping area. The groove width of the strip-shaped groove can be 0.75mm-0.85mm. The connection part connecting the damping area and the non-damping area in the connection area can limit the one-way connection of the damping area and the non-damping area. The length of the connection part (the non-shaded part of the connection area 112) parallel to the connection direction of the damping area and the non-damping area can be 4.45mm-4.55mm, and the width of the connection part is not more than 2.5mm. Of course, according to different oscillators, different damping area sizes and strip-shaped groove sizes can be set, which are not limited in this application. In addition, the distance of the circuit element relative to the side edge of the damping area parallel to the connection direction of the one-way connection is not less than 0.5mm, so as to avoid the circuit element being too close to the strip-shaped groove, and the distance of the circuit element relative to the side edge of the damping area away from the connection area is not less than 3mm, so as to facilitate the subsequent setting of the damping soft rubber.

Figure 2 A circuit schematic diagram of the frequency source circuit is shown in the drawings.

It is worth noting that the reference signal REF is input to the port REFin of the phase detector U1A after passing through the capacitor C8, the voltage-controlled oscillator Y1 outputs a frequency signal through the port Out, and the frequency signal can be input to the port RFinA of the phase detector U1A after sequentially passing through the resistor R1 and the capacitor C1, the phase detector U1A compares the phase difference between the frequency signal and the reference signal, and outputs a control signal to the port Vctr of the voltage-controlled oscillator Y1 through the port CP according to the phase difference, in addition, the port Vctr of the voltage-controlled oscillator Y1 is connected to one end of the capacitor C9, the other end of the capacitor C9 is grounded, the port Vctr is also connected to one end of the capacitor C10, the other end of the capacitor C10 is connected to one end of the resistor R3, and the other end of the resistor R3 is grounded.

It should be noted that the voltage-controlled oscillator Y1, the capacitor C5, the capacitor C9 and the capacitor C10 are more susceptible to vibration interference, and thus can be arranged in the damping region for isolation.

[0036] It should be noted that, since the vibration energy transmission direction is the preset direction, welding voltage-controlled oscillator and filter capacitor to damping area in a manner that element short side is parallel to preset direction can make element short side parallel to vibration energy transmission direction, so that the element short side of minimum stress is parallel to vibration energy transmission direction, reduce the deformation amount of element, and further reduce the influence of vibration energy on voltage-controlled oscillator and filter capacitor.

[0037] In another specific embodiment, as Figure 3 As shown, the target welding area corresponding to voltage-controlled oscillator in damping area can be provided with cross hollow area 114, and the slot width of the cross hollow area can be 0.55mm-0.65mm, which can further disperse the vibration received by voltage-controlled oscillator.

Since the tensile strength of metal indium is 2N / mm 2 , which is much lower than the tensile strength of ordinary solder alloy 48N / mm 2 , the material is softer, and raising circuit element can help reduce the influence of vibration on circuit element.
