SWRS166 – DECEMBER 2014
6.3.3 Transmission Line
The RF signal from the device is routed to the antenna using a CPW-G (Coplanar Waveguide with
ground) structure. This structure offers the maximum isolation across filter gap and the best possible
shielding to the RF lines. In addition to the ground on the L1 layer, placing GND vias along the line also
provides additional shielding
