RF antenna circuit protection

Circuit Protection of Antenna-RF type


Design Notes:
Protection application:
The communication signal from the antenna is usually 2.45 GHz when operating, and the magnitude is less than 1.0 Vp-p. Because these signals have high-frequency properties, the capacitance of the suppressor must be considered to avoid signal attenuation. There can be ESD electrical hazards.
Solution description:
As shown on the left, an ESD electrostatic protector is used to protect the antenna elements.
Supporting solutions: Not applicable.
Regulatory issues: IEC 61000-4-2 is the standard specification best suited for this circuit. This test proves that the end product is not vulnerable to ESD.
Characteristics: Not applicable.
Application warning: Not applicable.
