RF System

Modern RF systems consist of high-frequency analog electronics (the front end) and adaptive digital algorithms.

One of the primary challenges in RF system design is reducing the overall area, power, and cost for RF front ends—generally wireless transmitters and transceivers. For this reason, smart RF system design relies heavily on digital signal processing algorithms and control logic to optimize these performance factors and to calibrate and compensate for RF impairments.

Algorithms such as digital pre-distortion (DPD), automatic gain control (AGC), beamforming, and adaptive filtering are an integral part of today’s communications and radar systems. These RF system algorithms need to be designed together with models of the analog/mixed-signal components and RF front ends. Rapid system-level simulation is an essential requirement to efficiently explore design tradeoffs.

RF system designers’ typical tasks include:

  • Performing RF budget and corner analysis for the definition of the component specifications
  • Simulating the RF system, including digital signal processing algorithms and control logic
  • Building and validating RF models using measurement data

Rapid System-Level Design Simulation of Smart RF Front Ends

MATLAB® and Simulink® provide the required tools for supporting all the RF system design tasks, from system analysis to algorithm development and lab prototyping. Modeling and simulating RF, analog, and digital systems together enables faster development and easier debugging. The simulation speed achieved with circuit envelope simulation is the key enabler to managing the complexity of today’s wireless systems.
