What is Flatness?
2026-01-22
In RF power amplifier datasheets, you may often see specifications such as ±0.5 dB or ±1 dB.
Flatness is a key performance metric showing how consistently an amplifier maintains output power or gain across its frequency range, reflecting the product’s overall design quality and engineering. Lower flatness variation (e.g. ±0.5 dB) means more predictable behavior, especially in EMC, radar, and broadband test applications.
The illustration below helps you quickly understand what flatness really means.

Efficiency Impacts More Than RF Output Power
In RF system design, amplifier selection is rarely just about output power, gain, or frequency range. From a system engineering perspective, the real question is: How does amplifier efficiency impact the total system cost and integration complexity?

From L to Q Band: How to Choose the Right RF Power Amplifier for Your Application
When selecting an RF Power Amplifier (RFPA), many start with frequency. But in reality, frequency alone doesn’t determine the right solution. Different applications — radar, communication, jamming, or testing — require completely different amplifier characteristics.
