Power Density in radar applications, is typically described by the non-directional power density multiplied by the gain of the radar. Notice that the distance D is an exponential component to the equation, due to the three-dimensional "spreading" of the waveform as it propagates through space.

**Note: All of our calculators allow SI prefix input. For example, if you wish to input "25000000", just type "25M" instead. See the quick-reference table below for all compatible SI prefixes.

As a leading manufacturer and supplier of RF, microwave and millimeter-wave products, many industries around the world rely on Pasternack, including avionics, military electronics, IFF, SATCOM, ECM, industrial/manufacturing and oil/gas.

Pasternack has a large online library of free-to-use RF, microwave and millimeter wave calculators with formulas, including conversion tools, as with this power density calculator. These radio frequency calculators, conversions and formulas allow designers and engineers an easy-to-use method to find answers to your questions.

Typically used in radar applications, power density is described by the non-directional power density multiplied by the gain of the radar. The distance D is an exponential component of the equation, due to its three-dimensional 'spreading' of the waveform as it propagates through space. Our antenna Power Density Calculator is a measurement tool specifically designed for far-field calculations and will give power density, in Watts per square meter, at a given distance, output power and antenna gain.

To calculate the power density of an antenna, one must measure the power/square cm, in space, from the center of the antenna. Space is represented as a sphere with a radius 'R' - the distance from the center of the antenna. Power density is defined as the product of an isotropic antenna's power density and its gain, usually calculated in mW/cm2.

In each of the Pasternack’s product-oriented calculators, including this power density calculator, you can plug in formula variables for desired calculations. The RF power density calculator will then highlight a 'Find Related Products' button And then you can then choose the products that meet your specification.

Our wide selection of RF, microwave and millimeter wave calculators is part of our technical resource library. The power density calculator for RF as with the other Pasternack conversions and calculators with formulas, complements the Engineers Resource Center section on the website.
