Three Key Metrics for Power and Signal Quality — Continuous Power, Peak Power, and Harmonics

In the field of RF power amplifiers, Continuous Power, Peak Power, and Harmonics are the three core metrics for evaluating product performance.

In the field of RF power amplifiers, Continuous Power, Peak Power, and Harmonics are the three core metrics for evaluating product performance.

Continuous Power (CW Power) represents the output capability of a device during long-term stable operation. It directly affects system reliability and thermal design, and is commonly used in communication and continuous-wave applications.

Peak Power reflects the device’s instantaneous output capability under pulsed conditions. It allows the system to achieve higher power in a short time and is widely applied in radar and other pulsed systems.

In contrast, Harmonics focus on signal quality. They are the multiple-frequency signals generated due to device nonlinearity and are typically measured in dBc. Lower harmonic levels indicate cleaner signals, benefiting both electromagnetic compatibility and overall system performance.

In practical design, these three metrics are interrelated: higher peak power may result in increased harmonics, while raising continuous power imposes stricter requirements on efficiency and thermal management. Therefore, achieving a balance between power capability and signal purity is key to the competitiveness of power amplifier products.

70W Rack-Mount RF Power Amplifier-AVBR2080U48

The AVBR2080U48 is a solid-state broadband RF power amplifier based on Class AB architecture and RF GaN technology. It is specified for operation from 2.0 to 8.0 GHz, with a typical Output P1dB of 43 dBm.

SWR vs. Return Loss — How Do You Interpret Them?

VSWR and Return Loss often appear together in RF specifications. What do these two parameters actually tell us, and how should we interpret their values?

EMC TESTING IS MOVING HIGHER

Under UN Regulation No. 10 (07 series of amendments), the upper frequency limit for automotive radiated immunity testing has been extended from 2 GHz to 6 GHz, reflecting the growing integration of higher-frequency wireless and electronic technologies into modern vehicles.

4–8 GHz, Without Switching Amplifiers.

The AVBR4080H47 delivers 50W output power across the full 4–8 GHz frequency range, combining broadband coverage with high RF power in a single amplifier.

CW AMPLIFIER VS. PULSE AMPLIFIER

CW and pulse RF power amplifiers may have similar frequency ranges, but their power and thermal considerations can be quite different.
