Latest Patents

Leifso holds a patent for a "Quadrature frequency doubler with adjustable phase offset." This invention provides an improved frequency doubling circuit that features an adjustable phase offset. Instead of relying on traditional equations, the quadrature output signals are generated using mixers with input signals that are phase-separated by the same offset. This design minimizes the non-linearities introduced by the mixer, thereby reducing amplitude mismatch between the quadrature signals. Additionally, the phase offset can be tuned and calibrated using a phase-shifting circuit, allowing for a tuning range of approximately 5° in programmable steps. This combination of circuits effectively minimizes amplitude mismatch and phase errors, reducing interference during the transmission of image frequencies to the receiver's input.
