With a total of 3 patents to his name, Friesen has demonstrated a commitment to advancing the capabilities of electronic devices through innovative designs and solutions.
Latest Patents
Friesen's latest patents include the "Planar Magic-Tee Double Balanced Mixer" and the "Detector and Video Amplifier." The Planar Magic-Tee Double Balanced Mixer is a broad bandwidth mixer that integrates all circuitry on a single MMIC die. This design utilizes planar magic tee hybrids to minimize component quantity and die area, featuring a Lange coupler, capacitors, and quarter-wavelength transmission lines. The mixer topology employs a ring-configured diode quad with two magic tees at the RF and LO ports, along with a Wilkinson power divider at the IF port.
The Detector and Video Amplifier (DVA) is another significant invention by Friesen. This device includes a microwave monolithic integrated circuit (MMIC) detector processor that converts a modulated RF input signal into a baseband signal in video format. The MMIC amplifier, located on the same chip, amplifies the baseband signal to produce the video output. The DVA is temperature compensated and effectively detects signals across the full Ku band (12-18 GHz).
