1 Introduction

This guide is intended to be used in conjunction with the document ID PC-004159-DC version 3 from RANsemi.

This user's guide introduces a small cell application using Texas Instruments’ AFE7769D evaluation module (EVM) in collaboration with RANsemi, a semiconductor company that provides industry-standard systems on chips (SoCs) for small cell wireless infrastructure. This reference solution serves to help customers ramp system integration of the analog front-end (AFE), and allows for seamless interfacing with the RANsemi RNS802 SoC.

The AFE7769D is a 4T4R2F RF transceiver with integrated Digital Pre-Distortion (DPD) that serves to linearize power amplifiers (PAs) for improved wireless coverage to the end customer. The small cell 5-watt radio unit (RU) uses the EVM version of the device that connects with the RANsemi component of the solution for seamless interfacing. The RNS802 is a SoC that is designed for 5GNR/LTE small cell disaggregated and integrated RAN architectures, per RANsemi's website.

Note:

In the following sections, the code includes text like Picocom and PC802, as RANsemi was previously a part of Picocom before RANsemi became an independent company in November 2023. The names of the files were updated, but the hardware and software remain unchanged.
