Abstract

A radio frequency (RF) transmission line (100) is described. The RF transmission line includes a first ground line (106a), a second ground line (106b), and a signal line (104) disposed on a substrate (102) and forming a coplanar waveguide. A plasma limiter feature (108) is integrated into an internal surface of one or more of the first ground line (106a), the second ground line (106b), and the signal line (104). The plasma limiter (108) decreases a gap distance between the signal line (104) and the associated ground line. The gap distance is selected, together with a gas pressure, to control a voltage at which the gas within the gap breaks down, targeted at a breakdown power of 1 W across a wide bandwidth. The plasma limiter (108) thus limits a power transmitted by way of the RF transmission line (100) for protecting a sensitive integrated circuit (306).
