EMC TESTING IS MOVING HIGHER
2026-08-27
Automotive EMC testing is extending into higher frequency ranges.
Under UN Regulation No. 10 (07 series of amendments), the upper frequency limit for automotive radiated immunity testing has been extended from 2 GHz to 6 GHz, reflecting the growing integration of higher-frequency wireless and electronic technologies into modern vehicles.
For RF engineers, extending the test range from 2 to 6 GHz is not simply a matter of adding higher-frequency coverage. It places greater demands on the RF amplification chain, which must maintain sufficient output power, linearity and stability across a wider frequency range to generate the required test field.
This leads to an important distinction:
Rated power is not the same as usable power across the entire test band.
For EMC applications, the more meaningful question may be:
How much usable RF power can the amplifier deliver across the full frequency range?
As the test bandwidth expands, consistent output power across the frequency range can be just as important as the amplifier's maximum power rating.
So, when extending an EMC test system from 2 to 6 GHz, what becomes the biggest amplifier challenge: output power, linearity, or consistent broadband performance?

CW AMPLIFIER VS. PULSE AMPLIFIER
CW and pulse RF power amplifiers may have similar frequency ranges, but their power and thermal considerations can be quite different.

RF POWER AMPLIFIER INTERFACES & CONNECTORS
In RF systems, connectors and interfaces are often small parts of the overall design, but they still deserve careful consideration.
