Analog Filter Wizard ADI

Analog Devices 

Use the Analog Filter Wizard to design low-pass, high-pass or band-pass filters with actual op amps in minutes. As you progress through the design process, you can observe the characteristics of your filter design from ideal specifications to real world circuit behavior. Quickly evaluate the tradeoffs in op amp specifications-including gain-bandwidth, noise and supply current–to determine the best filter design for your requirements.

CapCad™

Dielectric Laboratories Inc. (DLI) DLI

DLI’s web based CapCad™ capacitor modeling software was developed to provide customers with an easy to use and readily accessible comparison tool for choosing the best Single-Layer, Multi Layer or Broadband Blocking capacitor to suit the customer’s needs. CapCad™ includes SPICE models with values that reflect typical performance at the chosen frequencies and temperatures that are of importance to an application. The user also has the ability to plot 2-port Scattering Parameters, Impedance, Q Factor or Equivalent Capacitance over any frequency span from 1 MHz to 40 GHz while maintaining the ability to adjust the temperature and note how it may affect the performance. CapCad™ also includes a Smith Chart utility and the ability to copy the S-parameter data in touchtone format (s2p).

Rejection Calculator

Custom MMIC Custom MMIC

This tool displays the contours of constant image rejection as a function of phase and amplitude error. After the user inputs a specific error condition, the program computes the image rejection and displays the result on the graph along with the contours. This visual representation allows the user to see which error is most significant, thereby offering a path to improved performance.

Mixer Spurs Calculator Spurs

José Luis Flores, AT4 Wireless

A new method for mixer spurs calculation has been developed which is easier and more straightforward to use than the traditional spurs chart approach when dealing with the frequency plan optimization in broadband double conversion transceivers suitable for applications as multi-band, multi-standard and Software Defined Radio. A full technical article describing this new method can be found here.

RF Inductor Comparison Tool

Coilcraft Coilcraft

This interactive online comparison tool for RF inductors replaces manual methods and helps prevent false starts in the design of new microwave and RF circuits. The user enters his/her operating frequency between 1 MHz and 3 GHz, then selects up to four inductors to compare using pull-down lists to pick the product series and inductance value. The results screen provides a table showing specifications for each part at the user’s own operating frequency: inductance, Q factor, impedance and equivalent series resistance (ESR). Below that, these same parameters are graphed to show performance over the 1 MHz to 3 GHz frequency range. Each part is plotted in a different color to make it easy to distinguish. And because they all appear side-by side on the same grid, it’s easy to quickly spot the best performer at any frequency.
