AVX VC06AG182R0CAT
AntennaGuard 0402/0603
AVX Low Capacitance Multilayer Varistors
ESD Protection for Antennas and Low Capacitor Loading Applications
GENERAL DESCRIPTION
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), 2 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.
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 Low Capacitance AG Series parts are
ideal solution for this type of applications as well as for many
more where low capacitance ESD protection is needed.

AVX VC06AG182R0CAT
AntennaGuard 0402/0603
AVX Low Capacitance Multilayer Varistors
ESD Protection for Antennas and Low Capacitor Loading Applications
Antenna Varistors
AVX offers a series of 0402 and 0603 chip varistors,
designated the AntennaGuard series, for RF antenna/RF
amplifier protection. These devices offer ultra-low capaci-
tance (<3pF in 0402 chips, and ≤3pF & ≤12pF in 0603
packages), as well as low insertion loss. Antenna varistors
can replace output capacitors and provide ESD suppression
in RF and capacitance sensitive applications.
It is very common to employ some form of a FET in many
types of efficient/miniature RF amplifiers. Typically, these RF
transistors have nearly ideal input gate impedance and
outstanding noise figures. However, FETs are very suscepti-
ble to ESD damage due to the very thin layer of SiO2 uses as
the gate insulator. The ultra-thin SiO2 layer is required to
improve the gain of the transistor. In other words, the upside
of the performance enhancement becomes the downside of
the transistors survival when subjected to an ESD event.
ESD damage to the RF Field Effect Transistors (FETs) is a
growing concern among RF designers due to the following
trends: (1) RF amplifiers continue to shrink in size, and (2)
FET gains figures continue to increase. Both trends relate to
decreasing gate oxide thickness, which in turn, is directly
proportional to increased ESD sensitivity. As miniaturization
trends accelerate, the traditional methods to protect against
ESD damage (i.e., PC board layout, passive filters, and diode
clamps) are becoming less and less effective.
AVX’s AntennaGuard varistor can be used to protect the FET
and offer superior performance to the previously mentioned
protection methods given above. The standard EIA 0603
chip size, and particularly the 0402 chip, offer designers an
ESD protection solution consistent with today’s downsizing
trend in portable electronic products. Savings in component
volume up to 86%, and PC board footprint savings up to
83% are realistic expectations. These percentages are based
upon the following table and Figures 1A and 1B.
