Cascaded Noise Figure Calculator
Pasternack's Cascaded Noise Figure Calculator computes the total noise and gain of cascaded amplifiers.
Complete RF Amplifier Design and Analysis Calculator
Given an amplifier or transistor's the S-parameters (scattering parameters), this calculator will analyze its stability, maximum gain, an even suggest a suitable conjugate L-matching network for a given load and source impedance of the circuit to which the amplifier will be connected.
Image Rejection Calculator
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
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.
Power Added Efficiency Calculator
Pasternack's Power Added Efficiency Calculator returns efficiency on an amplifier from input, output, and DC power.
Thermal Analysis Calculator
The thermal analysis tool tackles the problem of estimating the rise in temperature between the ambient surrounding and the bottom of a packaged MMIC when attached to a printed circuit board (PCB) without the need for a full 3D thermal simulation environment. With this tool, engineers can now develop a reasonable estimate of temperature at the bottom of a package based upon the construction of the PCB. Users simply select the package type, the power dissipation inside the package, the PCB board material, the via construction, and the base plate temperature (typically 85 ºC). The calculator then determines the temperature rise through the PCB to the bottom of the package, under the following assumptions: the PCB is plated with 1 oz. copper (1.4 mils thick), the package is attached to the PCB with solder (2 mils thick), and the base plate is an ideal heat sink. With this estimate, an engineer can then decide if a more detailed thermal analysis is required.
