Rogers high frequency PCB Ro4350B RF circuit boards

Rogers high frequency PCB application

PCB with RF (radio frequency) are an increasingly used technique within the Printed circuit board industry.

--A high frequency printed circuit board with works above 100 MHz.

--Works above 2 GHz radio frequency is a Microwave circuit board.

RF PCBs are used in different applications such as remote controls(wireless controls) smart phones,sensors, security,Amplifer,Radar etc.

New technologies make more and more use of these RF applications.This asks for a manufacturing according to high quality standards and
 choosing the right RF materials depending on the application.

What is the ideal RF( Radio frequency )PCB stack up?

It depends on your working frequency and target impedance. but in general rule you should avoid pushing the limits of pcb factory tolerances. for instance if you are using 50 ohm microstrips and your track width is 0.15 mm. this is not ideal because of manufacturing tolerances. at the end result this line could be a 0.12 or 0.18 mm. this is almost %20 change in width. so i always try to choose larger size than 0.5 mm tracks for micropstrips. also you should be careful about prepreg materials and resin content. other possible solution is manufacturing your pcb with impedance controlled.

When it comes to the ideal RF PCB stackup, various methods are used to PCB RF design that are microstrip, suspended strip, coplanar waveguide and grounding. You know, a microstrip consists of a fixed length of metal or wire and the under entire or part of the ground plane. Furthermore, the characteristic impedance of microstrip structure is basically from 50Ω to 75Ω.

There are some sample Stack up for your reference.
