Latest Patents
One of his latest patents is the "Outphasing power amplifier linearization method with improved output power back-off efficiency." This invention discloses a high-efficiency outphasing power amplifier capable of amplifying complex, wideband, multi-tone signals. The system can amplify at least 256 symbol QAM signals with negligible distortion while achieving high direct current-to-radio frequency efficiency at virtually all power levels. The outphasing amplifier employs a bridge output network formed from two complementary Class-D amplifiers to switch a DC supply voltage across the load. This design allows for high efficiency even at low power output levels.
Another significant patent is the "High power direct transmitter with frequency-shift keying (FSK) modulation." This invention features a high power, high efficiency voltage-controlled oscillator (VCO) that produces a modulated RF signal directly at the antenna. This innovation eliminates the need for driving stage power amplification and frequency translation, providing a low SWAP-C alternative to existing solutions.
