Latest Patents

One of Papananos' notable inventions is the "Method of Manufacture of a Passive High-Frequency Image Reject Mixer." This inventive solution presents a passive implementation of an image reject mixer (IRM) capable of operating at very high frequencies. It is manufactured using various silicon processes. The IRM comprises a quad MOS multiplier and a lumped-element hybrid, resulting in a passive IRM that operates at radio frequencies (RF) in the tens of GHz range, with an intermediate frequency (IF) of several GHz. The RF+ and RF− signals are fed into two quad MOS multipliers. A local oscillator signal (LO) provides LO+ and LO− signals to one of the multipliers, while a phase shifter takes the LO signal to generate a ninety-degree shifted LO+ and LO− signal for the other multiplier. By connecting the hybrids to the outputs of both multipliers and selecting an appropriate IF signal from each hybrid, the passive IRM functions effectively, showcasing Papananos' innovative design in high-frequency applications.
