AntennaGuard 0402/0603 AVX Low Capacitance Multilayer Varistors ESD Protection for Antennas and Low Capacitor Loading Applications GENERAL DESCRIPTION AVXs 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. AVXs 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 SiO gate insulator layer within the semiconductor. The 2 corresponding result of such a change increases the Power Amplifiers (PAs) 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.
