Amplifier With Semiconductor-Devices/Discharge-Tubes TRIZ Cases
- Remote RF Compensator Circuit for Multi-Band Antenna Fault Detection
Uses circulators, phase shifters, and shared cable power extraction to amplify multi-band RF signals while detecting antenna faults.
- RF Power Amplifier Module Coupler Layout for Low-Loss Combining
Modular RF amplifier combining uses an external coupler and shielded housing to cut combining loss while simplifying installation and calibration.
- Selective Group III Nitride Regrowth Using an Anti-Nucleation Mask
An anti-nucleation mask enables selective Group III nitride regrowth with different doping or composition while avoiding crystal damage and polycrystalline growth.
- LNA ESD Clamp Circuit for Millimeter-Wave RF Protection
An inductor-coupled ESD clamp protects a millimeter-wave LNA from antenna and supply ESD currents while limiting parasitic RF loss.
- Sample-and-Hold Recovery Circuit for Voltage Droop Compensation
An inverted AC compensation path offsets sample-and-hold capacitor droop to keep output voltage nearly constant during the hold interval.
- N-Polar HEMT Structure for Low Contact Resistance and Heat Dissipation
An N-polar HEMT uses graded AlGaN layers, 2DEG formation, and a diamond substrate to cut contact resistance and improve heat dissipation.
- RF Signal Processing Circuit for Doherty Back-Off Efficiency
Dynamic phase and amplitude control across RF amplifier branches improves Doherty transmitter efficiency under high power back-off.
