Electromagnetic compatibility (EMC) immunity testing evaluates device performance under different levels of electromagnetic interference. Amplifiers are critical for generating power levels strong enough to drive antennas to required field strengths, facilitating appropriate testing of equipment within EMC chambers. To ensure test accuracy and compliance with emerging high-frequency standards (6 GHz to 40 GHz), amplifiers must meet wideband range requirements, maintain linearity for signal integrity, and handle modulated signals efficiently.
This demonstration highlights how Maury Microwave amplifiers, power sensors, and interconnects support precise and reliable EMC immunity testing.
An MPA-series amplifier, specifically designed for EMC applications, amplifies a waveform from a signal source. With a frequency range from 400 MHz to 98 GHz, these state-of-the-art solid-state power amplifiers provide the wideband ranges and linearity required for modern EMC testing.
The LLC-series low-loss, high power bidirectional airline coupler receives the amplified signal and directs a portion to a 50-ohm load for termination and to the RTP5000 Series Real-Time Power Sensor for analysis. With industry-leading performance, the RTP5000 Series sensors measure, monitor, and verify power levels to maintain high integrity testing.
Additionally, StabilityPlusTM cable assemblies, which provide consistent phase and amplitude characteristics, are used to ensure highly accurate signal transmission in demanding, high-frequency EMC test environments.
