5G O-RAN RU, DFE, AFE Design Services
Azcom radio engineering team provides expertise for design of radio sub-systems, both in Analog and Digital domains. We have experience in designing O-RAN compliant 5G RU and LTE / 3G Remote Radio Head. Azcom owns a wide set of IPRs like Low PHY, Digital UP/DOWN conversion chains, CPRI/e-CPRI mapping, as well as a series of RF Front-End in different bands, to accelerate customer product development.
We support our customers in all the phases of the product development – design, development, prototyping, RF simulation and measurement, testing and certification.
