AD9361 Models

You can use the AD9361 models to simulate Analog Devices® AD9361 RF transmitter or receiver designs. These models also helps to see the impact of RF imperfections on your transmitted or received signal.

Install Analog Devices RF Transceivers using, simrfSupportPackages. You can open models using the Simulink® Library Browser and opening RF Blockset™ Models for Analog Devices RF Transceivers, or by typing the following in the MATLAB® command prompt:

open ad9361_models

Choose the model you want from the library:

Note

You require these additional licenses to run this model:

  • Communications System Toolbox™

  • Stateflow®

  • Fixed-Point Designer™

Complete documentation on how to use the models is available with the software download.

AD9361_TX Analog Devices Transmitter

Model Description

The transmitter model consists of three stages:

  • Digital up-conversion filters (DUC_Filters_TX))

  • Analog filters (Analog_Filters_TX)

  • RF front end (RF_TX)

You can use the transmitter model to simulate the following behaviors:

  • Tunable attenuation

  • Oscillator phase noise

  • Carrier-dependant noise floor

  • Attenuation and carrier-dependant non-linearities like output-referred third-order intercept (OIP3)

  • Attenuation dependant gain imbalance

  • Attenuation dependant local oscillator (LO) carrier leak

AD9361_RX Analog Devices Receiver

Model Description

The receiver model consists of:

  • RF receiver (RF_RX)

  • Analog filters (Analog_Filters_RX)

  • Analog to Digital Converter (ADC_RX)

  • Digital down-conversion filters (DDC)

  • Receiver signal strength indicators

  • Automatic gain control (AGC) state machine

  • Gain table

You can use the receiver model to simulate the following behaviors:

  • Tunable low-noise amplifier, mixer, and trans-impedance amplifier (LMT) gains

  • Carrier-dependent noise floor

  • Gain and carrier-frequency dependant non-linearities like output-referred third-order intercept (OIP3)

  • Gain and carrier-frequency dependant non-linearities like output–referred second–order intercept (OIP2)

  • Gain dependant gain imbalance

  • Gain dependant local oscillator (LO) carrier leak
