What distinguishes radio frequency (RF) printed circuit boards from microwave (MW) ones is the operating frequency: RF circuits in fact operate above 100 MHz whereas MW PCBs operate above 2 GHz.
The fields of application vary greatly, from smartphones to defence radars.
These circuits have a specific degree of construction complexity where, in other words, the admitted tolerances, especially on the impedance, are decidedly more restricted than those admissible on traditional PCBs.
This leads to the need for high precision of incision and narrow tolerances on the thickness of the dielectrics.
Small deviations from the admissible tolerances could generate disturbance both in the reception and transmission of radio signals.
The experience accrued over the years in manufacturing RF & MW printed circuit boards allows us to adopt the right solutions to help you build a high-performance, reliable and durable PCB.
