As the 5G revolution continues to unfold, with major wireless operators and OEM vendors conducting city level trials and products, it is becoming critical to ensure a smooth transition from 4G/LTE services to 5G services. Two key challenges in 5G systems relative to their 4G counterparts are coverage and directionality. To address the challenges related to 5G reduced range, beam directionality, and mmW-band operation, ED2 has developed an mmW 5G front end reference design. The reference design is intended to aid designers and makers to a fast proof of concept stage or quick prototype to demonstrate 5G waveforms and bridge between 4G/LTE and 5G services. Depending on your targeted scenario and detailed requirements, ED2’s reference design RF board can be configured to operate as an mmW repeater/relay and/or small base station.

Designers can simply design or purchase their own baseband radio/Software-Defined Radio, plug-in the mmW Front End, and start developing unique applications with a proven front end. The mmW Front End enables designers to quickly build high-performance systems with confidence and ease. By simply connecting the off-the-shelf mmW Front End to a baseband radio or SDR, end-user system development and debug time can be cut in half, while reducing the overall cost by 20% or more relative to standard design processes.
