When designing RF and microwave PCBs, you need to consider operating frequencies and choose materials that offer low losses. The frequency range of RF is 10 MHz to 1 GHz, and microwave is above 1 GHz.
RF circuits are prone to EMI, crosstalk, ringing, and reflections. To avoid these issues in your design, maintain consistent conductor dimensions to achieve uniform impedance. To reduce the current return path, incorporate solid ground planes right below the signal layer. This will increase the signal quality.
Consider distributed and lumped elements while designing transmission lines. Generally, a 50-ohm coplanar structure is used for minimum loss and maximum power transfer.
A signal experiences an impedance discontinuity when it passes through a via. If you’re stitching ground vias on the trace, understand the tradeoff.
Always partner with a capable RF and microwave PCB manufacturer and seek their assistance to create an efficient layout.
