Confused by RF Amplifier Datasheets? Start Here.
2026-06-25
When reviewing an RF power amplifier datasheet, it's easy to focus on headline specifications such as frequency range or output power. However, selecting the right amplifier often requires balancing multiple performance parameters rather than relying on a single number.
Specifications such as gain, efficiency (PAE), linearity, gain flatness, harmonic performance, and VSWR can all influence overall system performance, integration complexity, and long-term reliability.
To provide a quick overview of the most important considerations, we've created this RF Power Amplifier Selection Cheat Sheet, covering eight key specifications engineers should review during the amplifier evaluation process, along with several common selection mistakes and application-specific priorities.
While experienced engineers may already be familiar with these concepts, we hope this guide serves as a practical reference for those beginning their journey in RF and microwave engineering.

Understanding the difference between Small Signal Gain, Linear Gain, and Saturated Gain helps engineers evaluate amplifier performance with the right expectations—not just the highest number.

For broadband RF systems, the right amplifier selection depends not only on output power, but also on signal quality, integration needs, and operating conditions.

IMD, IP3 & OIP3 — Three RF Parameters That Are Often Confused
When an amplifier becomes less linear, it generates more IMD. Engineers use IP3 to estimate this linearity, while OIP3 expresses the same linearity at the amplifier output.

RFPA Module or Subsystem? Think Beyond the Product.
When selecting an RF power amplifier, many discussions start with the product. Experienced system engineers often start somewhere else.
