Description

Overview of EMC184040SE Low Noise Preamplifier

The EMC184040SE Low Noise Preamplifier is designed for high-performance EMI and EMC measurements across a wide operating frequency range of 18 to 40 GHz. With a minimum gain of 40 dB and a maximum noise figure of 5 dB, it ensures accurate, stable, and highly sensitive performance for demanding test environments. Although this model is discontinued, its replacement model is EMC184045, continuing the same high-quality design standards.

This amplifier is widely used in sectors such as automotive, avionics, military, wireless communication, consumer electronics, industrial electronics, power generation, and medical technology. Its ability to compensate for long cable losses, improve system noise floor flatness, and deliver high EMI performance makes it a trusted choice for compliance testing under international standards such as ANSI C63.4, CISPR 22 (EN 55022), MIL-STD-461, and others.

The rugged SMA connectors, compact housing, and integrated AC input power supply with grounding detect circuitry make installation and operation both safe and efficient. Multiple versions are available, including a bench model and mast-mount configurations with clamps and power supply cables, providing flexibility for different lab and field setups.
