RF Amplifier Gain Explained
2026-07-30
One of the most common mistakes when comparing RF amplifiers is assuming that gain is a single fixed specification.
In reality, the reported gain depends on where the amplifier is operating. A gain value measured under small-signal conditions can differ from the gain observed near the amplifier's maximum output power.
Without considering the operating region, two amplifiers with similar datasheet gain values may deliver very different performance in real applications.
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.
