Latest Patents

One of Patrick's notable patents is titled "Direct conversion receiver using a dithered local oscillator to mitigate adjacent channel coherent interference." This invention provides a direct conversion quadrature receiver and method. The receiver includes a primary local oscillator (LO) that down-converts a received RF signal to a quadrature intermediate frequency (IF) signal. Additionally, it features a dithering controller that responds to the quadrature IF signal generated by the primary LO. The feedback signal from the dithering controller controls the primary LO to offset the down-conversion of the RF signal, thereby reducing phase and gain errors in the quadrature IF signal.
