Wideband Power Amplifiers: Does Increasing Bandwidth Always Mean Lower Efficiency?
2025-08-05
In modern RF system design, achieving wide bandwidth, high output power, and high efficiency simultaneously remains a significant engineering challenge.
While amplifiers can be optimized for efficiency over narrow frequency ranges, extending performance across an octave or more often leads to issues such as:
· Significant efficiency drop-off at band edges
· Increased thermal management demands
· Stricter linearity and stability requirements
· Difficulty maintaining performance without bulky matching networks
These challenges are particularly critical in aerospace, electronic warfare, and broadband test systems.
Understanding and addressing these trade-offs is essential for advancing RF power amplifier technology, especially in demanding applications.
