Power Amplifiers TRIZ Cases
- Dual Directional Coupler Layout for Symmetric RF Coupling
Compensating mutual couplings in an asymmetric RF coupler layout restore forward/reverse symmetry, directivity, and tuning flexibility.
- RF Module IC Layout With Thermal Isolation for Stacked Circuits
A low-conductivity member and stacked dual-base layout block power amplifier heat, keeping RF module circuits compact and reliable.
- Multi-Loop ISM Transformer for Adaptive RF Gain and Matching
Selectable primary and secondary loops let one RF transformer tune attenuation and impedance matching as signal strength changes in wireless amplifiers.
- RF Power Amplifier Supply Switching With Segmented Capacitor Banks
Dynamic switching between segmented capacitor banks matches PA supply voltage to transmission power, cutting RF power loss and delay.
- Symbol-Based Envelope Tracking With Selective PA Fault Protection
Electronic circuit breaker switching isolates an overcurrent-faulty power amplifier while keeping other symbol-tracked amplifiers operating.
- Asymmetric Wilkinson Power Splitter With Integrated Impedance Matching
Combining signal splitting and inter-stage impedance matching cuts Doherty amplifier size, component count, and insertion loss.
- Asymmetric Wilkinson Power Splitter for Compact Doherty Amplifiers
An integrated asymmetric Wilkinson splitter combines signal division and impedance matching to cut Doherty amplifier size and insertion loss.
- Integrated TR Switch With ESD Topology for Low-Noise Transceivers
Integrated TR switching with configurable ESD diodes cuts BOM cost while limiting RX-path interference and noise figure impact.
- Multi-Output NRHPZ Power Converter for Fast RF Supply Modulation
A multi-output NRHPZ converter combines switched-capacitor and magnetic stages to track fast RF envelope changes without RHPZ limits.
