Example Embodiment
[0025] Example one:
[0026] See figure 1 This embodiment shows a radio frequency port electrostatic protection circuit, which can conduct electrostatic protection on the radio frequency port without affecting the radio frequency performance of the radio frequency port.
[0027] The radio frequency port electrostatic protection circuit of this embodiment includes: a radio frequency port 11, an electrostatic protection circuit 12, and a radio frequency circuit module 13;
[0028] The electrostatic protection circuit 12 includes a low-frequency lead-out circuit 121 and a low-frequency filter element 122. The low-frequency filter element 122 is connected between the radio frequency port 11 and the radio frequency circuit module 13, and is used to perform low frequency filtering on the signal transmitted to the radio frequency circuit module 13. One end of the derivation circuit 121 is connected between the radio frequency port 11 and the low-frequency filter element 122, and the other e...
Example Embodiment
[0041] Embodiment two:
[0042] See Figure 4 , This embodiment shows a method for protecting radio frequency port static electricity, including:
[0043] S401. The radio frequency port receives the input radio frequency signal, and transmits it to the back-end circuit through the connection line;
[0044] S402. The low-frequency filter components connected to the radio-frequency port and the radio-frequency circuit module filter the low-frequency signal in the radio frequency signal;
[0045] S403. The low-frequency derivation circuit with one end connected to the radio frequency port and the other end grounded introduces the low-frequency signal into the ground plane, where the low-frequency derivation circuit is equivalent to an open circuit for high frequency signals, and is equivalent to a short circuit for low frequency signals.
[0046] In this embodiment, the low-frequency derivation circuit may include components for opening the high-frequency signal and short-circuiting the l...
