Tools & Simulations

IBIS Model 1

ADIsimRF

ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.

Open Tool

ADIsimPLL™

ADIsimPLL enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL Synthesizer design and simulation tool available today. Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market.

ADF4351 Evaluation Board

Buy Now View Details

Features and Benefits

  • Self-contained board including PLL, VCO, loop filter (35 kHz), 25 MHz TCXO reference, USB interface, and voltage regulators
  • Accompanying software allows control of synthesizer functions from a PC
  • Choice of power supply via USB or external feeding
  • Typical phase noise performance of −104 dBc/Hz @ 3 kHz offset from carrier (1 GHz output frequency)

Product Details

This board is designed to allow the user to evaluate the performance of the ADF4351 frequency synthesizer for phase-locked loops (PLLs). It contains the ADF4351 integrated synthesizer and VCO, SMA connectors for the output signal, power supplies, a reference oscillator, and an USB connector. There is also a loop filter (35 kHz) on board. The evaluation board is set up for a 25 MHz PFD comparison frequency. An on-board TCXO provides the 25 MHz reference frequency.

The package also contains Windows® software (XP or later) to allow easy programming of the synthesizer.

AD-FMCOMMS6-EBZ

AD-FMCOMMS6-EBZ Evaluation Board

Buy Now View Details

Features and Benefits

  • Reduces receiver complexity and the number of stages needed, increasing performance and reducing power consumption 
  • Avoids image rejection issues and unwanted mixing 

Product Details

The AD-FMCOMMS6-EBZ eval board is a 400MHz to 4.4GHz receiver based on the AD9652 dual 16bit analog to digital converter, the ADL5566 High Dynamic Range RF/IF Dual Differential Amplifier and the ADL5380 quadrature demodulator.

This is an I and Q demodulation approach to direct convert (also known as a homodyne or zero IF) receiver architecture. Direct conversion radios perform just one frequency translation compared to a super-heterodyne receiver that can perform several frequency translations. One frequency translation is advantageous because it:

  • Reduces receiver complexity and the number of stages needed, increasing performance and reducing power consumption
  • Avoids image rejection issues and unwanted mixing


This topology will provide image rejection and early implementation of the differential signal environment. There is an amplification stage to maintain the full-scale input to the ACD. The local oscillator and ADC clock are on board and share the same reference signal prevent smearing. The form factor is VITA57 compliant and all of the DC power is routed from the data capture board through an FMC connector. This evaluation board demonstrates a high performance receiver signal chain aimed at military and commercial radar using “commercial off the shelf” (COTS) components. The overall circuit has a bandwidth of 220MHz with a pass band flatness of +/_ 1.0 dB. The SNR and SFDR measured at an IF of 145MHz are 64dB and 75dBc, respectively.

Product Details

The AD-FREQCVT1-EBZ is an add on board for the FMCOMMS3/4/5 boards which contain the AD9361. While the complete chip level design package can be found on the ADI product pages, information on the card, how to use it, the design package that surrounds it, and the software which can make it work, can be found on the analog wiki site.

The purpose of the AD-FREQCVT1-EBZ is frequency up or down conversion to allow the AD9361 to operate down to 1MHz.
