ESD Protection Of Antennas In The Communications Industry

An antenna is a converter that converts guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium (usually free space),or vice versa. Engineering systems such as radio communications,radio,television,radar, navigation, electronic countermeasures, remote sensing, radio astronomy, etc., all use electromagnetic waves to transmit information, all rely on antennas to work.

The communication signals emitted by the antenna operate at radio frequencies of 900, 1,900 (DECT), 2,400, and 5,800 MHz and have a magnitude less than 1.0 Vp-p. Due to the high frequency nature of these signals, the capacitance of the suppressor must be considered to avoid signal attenuation.

 This solution complies with IEC61000-4-2 air 15KV contact 8KV.

     For ESD protection, you can use PGB polymer anti-static series 0603 packaged devices, or you can use the pressure-sensitive 0402 packaged device ESD040224VP080. Yint can also provide TVS SOD882 packaged devices with lower clamping voltage for protection. Please contact us for details.
