In this episode Shahriar takes a deep dive into near-THz sub-harmonic mixers. To demonstrate the concepts, measurements and teardowns a set of Tektronix Sub-Harmonic mixers have been acquired (WM 490-F & WM 490-W) which operate from 90-140GHz & 75-110GHz respectively. This video is organized as follows: 00:00 - Introductions 00:50 - Acquired near-THz sub-harmonic mixers & diplexers 01:26 - Theoretical background, non-linear devices, harmonic generation 06:05 - Spectrum analyzers utilizing sub-harmonic mixers, signal ID 08:27 - Tektronix sub-harmonic mixer design, schematic & principle of operation 15:11 - Mixer diode characterization using Keithley SMUs & I/V tracer application 19:59 - Mixer teardown, analysis and microscope view of THz diode 28:07 - Diplexer architecture & characterization using a 4-port Siglent network analyzer 33:24 - Complete near-THz down-conversion setup using a x6 mm-wave multiplier source and Tektronix MSO68-B oscilloscope, conversion loss, harmonic number verification, signal ID process 45:35 - Using a ~100GHz carrier to determine the RPM of an optical chopper 48:15 - Concluding remarks Please consider supporting The Signal Path: https://www.TheSignalPath.com/Donate   / thesignalpath   Other links: https://www.TheSignalPath.com   / thesignalpath
