RF5G RF Transceiver: AD9375 and Alternatives
Advertisement
This application note covers 5G Transceiver basics, focusing on the AD9375 5G RF Transceiver from Analog Devices Inc. This transceiver is designed for both transmitting and receiving using 5G frequency bands.
It also mentions other manufacturers and vendors of 5G transceivers.
About 5G
5G represents the fifth generation of wireless technology, standardized in 3GPP release 15 and later. It surpasses previous 4G standards like LTE, LTE Advanced, and LTE Advanced Pro. 5G finds application in both cellular communication and IoT (Internet of Things) devices. It supports a wide range of frequency bands, including:
- Sub 1GHz
- 1 to 6GHz
- Above 6 GHz (millimeter wave frequencies)
5G transceivers operate within these same frequency ranges.
