Does anyone have any experience using zero-ohm resistors in an RF signal path to select antennas?

I've typically used RF switches for this purpose, but that's also when it was necessary to allow the antenna selection to be changed "in the field". But for cases where the antenna selection is a manufacture-time option, I'm considering simple zero-ohm resistors.

I highly recommend using a normal SMD 10pF to 100pF ceramic capacitor, depending on frequency. They’re already used on the board, and tend to be cheaper than zero-ohm resistors, as we buy them by the bazillion rather than the handful.

What are primary and secondary sides of PCB?

I am designing a 2 layer PCB with components on both side of it. SMT components are one one side of PCB, but TH (door gat) components are on both sides. I need to understanding something mentioned by the supplier called primary and secondary sides.

What are some of the benefits and downsides of moving from a two layer PCB with components on a single side, to a four layer PCB with components on both sides?

We got a quotation sheet of four layers board but it greatly exceed our budget. So now we are thinking about reduce layers to save cost. Does this solution work?

Hoe ontwerpen we een printplaat met SMT-componenten voor assemblage??

I am a junior electrical engineer and last week I have joined a product develpment project which involves SMT PCB. Would you like to share some general steps about designing PCB?
