Advanced 5G Radiohead Design

An antenna array the size of your palm may cover one side of a radiohead module with beam steering RFICs, transceivers, and power amplifiers (PAs) driving them from the reverse side of the PCB. Such compact high-frequency modules demand technology-aware design platforms that support discrete and embedded RF component design and system integration with in-design electromagnetic (EM) and thermal analysis, RF circuit simulation, and workflow support for co-design of ICs, IC packages, and modules with GaAs, GaN, and Si technologies.

Cadence helps you address these high-frequency needs with the following:

  • Intelligent System Design:  Using Virtuoso Heterogeneous Integration for RF and AWR Design Environment platform for RF MMIC and PCB IP development with in-design multiphysics analysis software helps engineers through an integrated design platform across the entire chip, package, and PCB system.
  • Support for 5G digital functions: RF digital ICs functions such as decimation, clipping, and digital pre-distortion enabled by Virtuoso Digital Implementation working with the Virtuoso Heterogeneous Integration for RF through a common OpenAccess database and Cadence Spectre Simulation Platform.
  • System-level designs: Develop system-level designs and detailed evaluations of digital pre-distortion algorithms through Cadence Visual System Simulator (VSS) co-simulating with RF PA IP from Microwave Office software and/or Cadence Spectre RF Option.
  • Smaller form factors: Optimize performance and cost using the Allegro X PCB Designer ecosystem with mechanical CAD partners.

Revolutionize Network Operations

In a centralized or cloud radio access network (C-RAN), baseband cabinets move from the bottom of mobile operator masts to edge-computing facilities in the fronthaul, where centralized baseband can be dynamically shared between radioheads. Massive co-located artificial intelligence (AI) optimizes the baseband performance over widely varying radiohead installations and traffic and provides AI heavy lifting for robots, drones, and other user equipment.

5G baseband and high-performance computing (HPC) meet in mobile edge-computing centers, and like HPC, the latest digital, network, and machine learning (ML) technologies are driving the market.
