ESD Protection for Antennas and Low Capacitor Loading Applications
Antenna varistors offer excellent ESD repetitive strike capa-
bility compared to a SOT23 diode when subjected to IEC
61000-4-2 8Kv contact discharge. A performance summary
is shown in Figure 2.
ESD TEST OF ANTENNAGUARD RATINGS
Antenna varistors also turn on and divert ESD overvoltages
at a much faster rate than SOT23 devices (typically 300pS
vs 1500pS - 5000pS). See Figure 3.
The equivalent circuit model for a typical antenna varistor is
shown in Figure 4.
The varistor shown exhibits a capacitance of ≤3pF which
can be used to replace the parallel capacitance typically
found prior to the antenna output of an RF amplifier. In the
off state, the varistor acts as a capacitor and helps to filter
RF output. The varistor is not affected by RF output power
or voltage and has little insertion loss. See Figure 3.
