In the fields of electromagnetic testing and RF measurement—spanning everything from chip-level electromagnetic compatibility (EMC) testing and antenna/radar system performance evaluation to the characterization of electromagnetic material properties—the RF power amplifier (PA) serves as a critical piece of equipment.
Signal sources (such as signal generators and vector network analyzers) typically output low-power signals in the milliwatt range, which are far from sufficient to drive many testing scenarios. This is where the power amplifier plays a vital role: it amplifies the weak output from the signal source to the required power level without distortion, providing precise and stable drive signals for a wide range of demanding testing applications.
Typical Test and Measurement Applications
1. Electromagnetic Compatibility (EMC) Testing
Specific requirements for power amplifiers in EMC testing:
|
Requirement |
Description |
|
Ultra-wide frequency coverage |
EMC standards span a vast frequency range from kHz to GHz |
|

Ensures test signal purity and prevents harmonic interference with test results |
|
Gain flatness |
Maintains stable gain output across the entire frequency band |
|
Continuous Wave (CW) full-power operation |
Requires sustained full-power output over long periods |
|
High VSWR tolerance |
Antennas and coupling devices may exhibit severe impedance mismatch at various frequencies |
|
Open/short-circuit survivability |
Operates safely even under open-load or short-circuit conditions |
