RF & EMC Power Amplifiers
Low Noise to High-Power Pulsed Amplification Across the Full RF and EMC Test Chain
An EMC or RF test chain has multiple distinct points where amplification is needed, each with very different requirements — a low-noise stage ahead of a sensitive receiver, a continuous-wave power stage for radiated immunity testing, and a high-peak-power pulsed stage for radar simulation are fundamentally different amplification jobs. RFlight's standalone amplifier range spans all of these, from low-noise front-end amplification through to the highest-power pulsed radar simulators, covering 4kHz up to 60GHz across seven distinct rack-mount and bench product families.
WLNA low noise amplifiers boost weak received signals ahead of a spectrum analyzer or receiver, where noise figure matters more than raw output power — the receive-side counterpart to the power amplifier families below. NTWPA cabinet/chassis amplifiers are rack-mount power stages purpose-built for radiated immunity test systems. CW power amplifiers split across three ranges — low-frequency (4kHz-1GHz), mid-band (0.7-6GHz), and high-band (1-60GHz) — deliver the continuous-wave power IEC 61000-4-3 radiated immunity testing requires at everything from bench-scale to full anechoic chamber testing.
Pulsed power amplifiers, split by mid-band (80MHz-8GHz) and high-band (8-18GHz X/Ku), provide the short-duration peak power that radar susceptibility and MIL-STD immunity programmes require, available in both solid-state and travelling-wave tube designs depending on the peak power and frequency needed. Every family in this range is a ready-to-use rack-mount or bench instrument, built to drive a test antenna or fixture directly — for OEM gain blocks or LNA modules to integrate into a custom chain instead, the standalone RF Amplifier Modules series covers that different integration need.
Frequently Asked Questions
How do I choose the right CW power amplifier frequency band for radiated immunity testing?
The choice depends on the frequency range your test standard requires — IEC 61000-4-3 and similar radiated immunity standards specify frequency coverage requirements, and matching that requirement to the low-frequency (4kHz-1GHz), mid-band (0.7-6GHz), or high-band (1-60GHz) family ensures the amplifier covers the actual frequencies your test programme needs.
When would I need a pulsed amplifier rather than a CW amplifier from this range?
Pulsed amplifiers are needed specifically for radar susceptibility testing and MIL-STD pulsed immunity programmes, which test with short, high-peak-power bursts rather than sustained output — a fundamentally different test requirement from continuous-wave radiated immunity testing, which the CW amplifier families are built for instead.
What's the difference between this range and the RF Amplifier Modules series?
This range consists of complete, ready-to-use rack-mount and bench instruments built to drive a test antenna or fixture directly. The RF Amplifier Modules series instead provides OEM board- or chassis-level gain blocks meant to be integrated into a custom-built system by an engineer or integrator, rather than used as a standalone instrument.
