Circuit Protection of Antenna

Design Notes:

Protection Application:
The communication signals carried by the antenna operate in the radio frequency ranges of 800 – 950 MHz and 1,800 – 1,900 MHz, and are less than 1.0 Vp-p in magnitude. Due to the high frequency nature of these signals, the capacitance of the suppressor must be taken into account to avoid signal attenuation. The electrical threat will be ESD.
Solution Description:
As shown at the left, a single PulseGuard® suppressor is used to protect the antenna element.
Companion Solutions:
Does not apply.
Regulatory Issues:
The IEC 61000-4-2 will be the most appropriate standard that applies for this circuit. It supplies a test method for verifying that the end product is not susceptible to ESD events.
Unique Features:
