Abstract: | We demonstrate that narrow-band tuned circuits may be used for ESD protection of RF inputs, and a figure of merit for optimization of these circuits is presented. The performance of the ESD-protected RF circuit is dependent on the quality factor of the ESD device, and various protection devices are evaluated in this work. Record-breaking human body model (HBM) protection levels, exceeding 5 kV, have been achieved without significantly degrading the RF performance at 5 GHz. Broadband circuit protection is also addressed. |
