AntennaGuard 0402/0603
AVX Multilayer Ceramic Transient Voltage Suppressors
ESD Protection for Antennas and Low Capacitor Loading Applications
GENERAL DESCRIPTION
RF antenna/RF amplifier protection against ESD events is
a growing concern of RF circuit designers today, given the
combination of increased signal “gain” demands, coupled with
the required downsizing of the transistor package. The ability to
achieve both objectives is tied to a reduced thickness of the
SiO₂ gate insulator layer within the semiconductor. The
corresponding result of such a change increases the Power
Amplifier’s (PA’s) vulnerability to ESD strikes — a common event
with handheld electronic products with RF transmitting and/or
receiving features.
AVX’s 0402/0603 AntennaGuard products are an ultra-low
capacitance extension of the proven TransGuard^® TVS (transient
voltage suppression) line of multilayer varistors. RF designers
now have a single chip option over conventional protection
methods (passive filters with diode clamps), which not only gives
superior performance over traditional schemes, but also
provides the added benefits of reduced PCB real estate and
lower installation costs.
AVX’s AntennaGuard products are available in capacitance
ratings of ≤3pF (0402 & 0603 chips) and ≤12pF (0603 chip).
These low capacitance values have low insertion loss, as well as
give other TransGuard^® advantages such as small size,
sub-nanosecond response time, low leakage currents and
unsurpassed reliability (FIT Rate of 0.2) compared to diodes.
