I plan to use the amplifier ADL5324 in my design and my target frequency is 3400 MHz. The datasheets reports the component placement in mils (for each band) on a FR4 PCB. My board will be an FR408 board (4 layers) and the distance of the ground plane from the microstrip is only 0.17mm, implying a 50 Ohm line to be only 0.35mm wide.
I would like:
- Since there are many FR4 specifications, to have an help expressing the component placement in Electrical Length [deg]
- To know if the microstrip line so thin could affect the performance and/or should be taken into account in the layout process.
