Most common radiated immunity standards include IEC/EN 61000-4-3, MIL-STD 461 RS101/03/05, SAE J113/4, ISO 11451-2, ISO 11452-4/5 and CISPR 20. These standards require the use of several different antennas.
Formulas and Calculations
Here is a calculation tool to help determining the actual field intensity or power density at a given distance.
Article
This article explains different power amplifier / antenna matching combinations for some new RF immunity standards. Though far from certain, it looks as if 6 GHz is a strong canidate for the upper frequency for consumer products.
Formulas and Calculations
Here is a handy page to convert units from dBm to to Volts to Watts based on a 50 ohm system.
Test Guide
This test procedure describes how the small signal performance data of an amplifier is gathered and checked against previously recorded data. This is a fault finding step that establishes the health of the preamplifier.
Formulas and Calculations
This tool will calculate the maximum coverage that the antenna will cover from a specified distance and antenna's half-power beamwidth.
