On the wireless side, the emphasis is on maximizing power density and getting to as small a solution as possible to reduce the overall size of 5G applications or provide flexibility to incorporate additional capabilities or functionality. Operating in a smaller space translates to functioning more cost effectively and more efficiently.
Possible options and advances in wireless communications technology are endless. ADI’s deep domain knowledge spans across industries and technologies, providing perspectives and solutions to meet these systems’ growing demands. Insights include alternative ways of system packaging to impact size, weight, and power that produce a smaller footprint, lower component count, and smaller board area impact. Reducing the board’s size has the added value of freeing up space to include new technologies or additional functionality such as artificial intelligence (AI) and speech recognition.
Lower noise systems require less shielding;
less shielding requires less weight and smaller size.
ELIMINATING THE NOISE
Electronic technology products require a variety of voltages and currents to operate. Efficient power conversion is key to a well-run system. This means high frequency switching power conversion is needed. A drawback to high frequency switching is the generation of electromagnetic noise interference (EMI) in the RF range. This EMI interference can disrupt the function of highly sensitive devices such as the RF transceiver embedded in a 5G network. ADI’s Silent Switcher® series of power converters operate at high frequency while maximizing efficiency—generating the industry’s lowest electromagnetic interference (EMI). This results in a more robust communication link in cellphone network equipment.
The 5G radio installation is responsible for delivering cell and internet service worldwide, allowing workers, friends, and family to stay in touch. The promise of a globally connected future will undoubtedly have a massive impact on how the world’s population will live, learn, work, and play. Fifth generation wireless technology will require significant advances in power electronics to achieve this goal. And, reliability will be critical, as lives may depend upon it.
