Amplifier Modifications To Raise Efficiency TRIZ Cases
- Doherty Amplifier Neutralization Circuitry for Distortion Reduction
Neutralization circuitry cancels parasitic feedback in Doherty amplifiers, resolving the power versus distortion trade-off.
- Symmetric Doherty Amplifier Phase-Shifted Load Modulation
Phase shift circuitry in a symmetric Doherty amplifier adjusts VSWR to resolve the trade-off between maximum RF power and high output back-off efficiency.
- Amplifier Circuit Variable Voltage Power Supply
Variable voltage power supply tracks signal amplitude to reduce power loss in battery systems.
