High Frequency Amplifiers TRIZ Cases
- Reconfigurable Passive Power Divider for Inactive Path Isolation
Switchable passive routing blocks power to inactive paths, reducing loss while preserving divider and combiner operation.
- InGaP HBT Collector Structure for Low Interface Resistance
Lower-ordering InGaP collector layers cut interface resistance and carrier depletion while preserving breakdown voltage in rugged RF HBTs.
- Cascode Wideband RF Outputs With Tee-Filter Port Isolation
Split cascode outputs with tee-filters and inductive isolation separate wideband RF ports to limit interference and improve signal-to-noise ratio.
- PMIC Multi-Voltage Generation Using a Single DC-DC Inductor
Time-divided voltage generation lets one DC-DC inductor supply multiple PMIC voltages concurrently, cutting footprint and circuit complexity.
- RF Amplification Circuit With Coupled Coils for Multi-Band Tuning
Magnetically coupled coils and switchable amplifier paths retune resonance for multi-band RF operation while keeping bandwidth stable.
