RF and radar work gets messy fast when units are not explicit. These pages keep the frequency, power, distance, and decibel relationships easy to audit.
Use this category for the flagship RF workflow: dB and power-unit cleanup first, propagation and path loss second, then link budgets, received power, and radar checks where relevant.
Start with the guide that gives the clearest method, then move into the live tools once you know which figures matter.
A practical guide to watts, dBm, power ratios, and decibels, focused on building intuition for logarithmic RF units before you try to read a link budget or a bench measurement.
Use the guide hub when you need the formula, worked example, or explanation before you run the numbers.
A practical guide to watts, dBm, power ratios, and decibels, focused on building intuition for logarithmic RF units before you try to read a link budget or a bench measurement.
A practical guide to free-space path loss, wavelength-aware intuition, and feedline loss, built to explain what the loss figure really means before you roll it into a larger RF or microwave link budget.
A practical guide to RF link budgets and received power that treats every gain and loss term as an accounting decision, making it easier to see whether a link is viable and where the margin is being won or lost.
Keep the most useful formulas, examples, and checks available offline with the printable packs for this category.
A denser offline guide to dB, dBm, watts, power ratios, and the conversion habits that make RF budgeting less error-prone.
A printable guide linking frequency, wavelength, and basic antenna lengths, with unit prompts for common RF ranges.
A stronger revision pack for free-space path loss, received power, link accounting, and the practical dB habits that turn path numbers into usable RF planning decisions.
