This eBook covers the design considerations for PCB laminate circuits and how to take these issues into account when designing for mmWave applications. Dielectric constant is a key material parameter that can vary due to temperature changes, within a substrate material due to the construction material, or over frequency. Dissipation factor is another key parameter that can affect the losses in a circuit and become very significant at mmWave frequencies. Metal surface roughness is another important consideration that can increase signal loss that is not significant at lower frequencies. The woven glass within the circuit material also causes changes in dielectric constant that can affect mmWave signals differently depending on the direction of the metal transmission lines. In addition, datasheets might not provide all of the information you need to simulate a circuit accurately.

As the RF spectrum becomes more crowded, the chance for interfering signals greatly increases as frequency bands become very close to each other and sometimes even overlap. There are many techniques from filtering to spectrum sharing to frequency cancelation. This eBook has five articles that cover various aspects of interference. The first takes a look at the Wi-Fi or 5G question – do we need both and how they use the same frequencies in some cases. The second article looks at a new self-interference cancelation method for co-location of radio transceivers so they can share the same frequency band. The third looks at a growing technology for 5G called Dynamic Spectrum Sharing that allows LTE and 5G signals to use the same frequency band. The next article is a short discussion about how the unlicensed bands may become a key factor in the rollout of 5G. The last article takes a look at 5G mmWave filtering and the challenges to designing good filters at these higher frequencies.

As 5G, Wi-Fi 6 and various IoT connectivity standards roll out together, many people wonder how these technologies will work together to benefit businesses and consumers.
