- At the page 22 of the QPF0219 datasheet, it is said that Rogers 4003C is recommended to use for the fabrication of the EVB. However, the stack-up diagram shown in the EVB’s schematic and layout files uses TACONICS RF-35HTC . May I ask which stack-up is better?
(Quoted from the datasheet: Multilayer PCB, top RF layer is 8 mils thick Rogers 4003C (εr = 3.35). Metal layers are 0.5 oz. copper. The microstrip line at the connector interface is optimized for the Southwest Microwave end launch connector 1092-01A-12.) - May I kindly ask if the layout design files for the QPF0219 EVB are available? I’m referring to the original PCB design files (e.g., Cadence Allegro format), not just the Gerber files.
