Amplifier Details To Increase Power/Efficiency TRIZ Cases
- Power Amplifier Module Layout for Heat Dissipation and Harmonic Control
A branched pad-and-wiring layout spreads heat in a compact power amplifier module while supporting harmonic termination and output matching.
- Predictive Slew-Rate Control in Analog Output Circuits
A predictor adjusts analog output slew-rate limits ahead of fast transitions to cut power dissipation while maintaining distortion-free output.
- Segmented RF Output Array for Uniform Thermal Loading
Non-uniform loading across segmented RF amplifier output groups evens heat distribution to improve linearity, gain, and reliability.
- Class D Half-Bridge Switching Circuit With Resonant Dead-Time Reduction
Auxiliary switches use parasitic capacitance resonance in a class D half-bridge to cut switching loss and dead-time distortion.
- Wideband Cascode Bias Circuit for Envelope-Tracking Amplifiers
A capacitor-coupled cascode bias circuit extends bandwidth under modulated supply voltage, improving PA efficiency while isolating output.
- Power Amplifier Bias Current Rerouting for Gain Dispersion Control
As supply voltage drops, bias current is diverted to the matching circuit to control gain dispersion in envelope-tracking power amplifiers.
