Excellent presentation on what I and many other perceive as a very complex topic.
Why are the bias tees necessary in the circuit? It couldn't work without them?
thanks so much for the clear and detailed info!
Part of what this guy is saying doesn't make sense
Undoubtedly the best explanation of RF/Microwave mixers!
thank you for sharing sir
Great talk. Thank you very much. I am working on my master's thesis at the moment. We had IQ mixers in our courses, but they were poorly and not entirely explained. This helped a lot. I am even using a Marki IQ mixer, seems like a great company.
It’s just trigonometry. Multiplying sines and cosines of various frequencies.
What I hate about enineering is that we talk all this math and "procedures" but how the hell are you supposed to implement this crap? As an ECE Senior with a 3.8 GPA, I feel like i have alot of useless information that I can't do anything with because schools do a horrible job at application. I feel like I wasted a few years out of my life that i'll never get back. Engineering Schools are the worst.
Well, buy the components from these guys, and then you don’t have to worry about it. It’s just like playing with Legos.
thanks for the detailed video making.
Wow ..just wowo ..slide 6 is great for me
Awesome! Thank you for sharing!
This is incredibly valuable and educational. Thanks Marki!
wonderful talk
Actually.. I’d love the see a course on the use of a spectrum analyzer in “ham” , public safety and commercial radio. I would like to get more out of spectrum analyzer units other than just tuning the occasional duplexer,. (Same win oscilloscope use) Thanks again!
Excellent presentation.👍🏻! In fact, my wife enjoyed it as well. The;She is now looking forward to the next video in the series... “Blenders and Juicers” 😆 😂🧂👍🏻
I love this.
I was actually disappointed when I realized the tall ended 4 mins earlier than thought xD I love your industry insights, you probably have one person more getting more into HF electronics!
awesome to listen to!
Very valuable, thank you very much. I‘m also planning my entrepreneurial path and always thankful for such insights
Such an inspirational talk, thank you to the speaker and for uploading this video.
Voice is not audible. I had difficulty understanding what is being said
finally, someone talks about mixers in the correct info, well done!!!
Oh, and I think a discrete t flip flop is used in the softrock SDR
The discrete flip flop creates square waves. How does this impact the performance of such a mixer? It seems like it would cause a lot of sideband noise/interference.
I've always thought of I and Q as sine and cosine. With control over both you can put your signal anywhere with the circle your modulation bandwidth allows.
Exactly. That’s what it is. Basically your signal is on a ribbon, and your sine and cosine create a rotating unit vector. When you send your signal through the mixer, the mixer twists the ribbon at a twist rate equal to the frequency of the local oscillator. The two outputs then slice the twisted ribbon in the horizontal and vertical direction. The two new signals on the vertical and horizontal slices both consist of signals which are the sum and different between the frequencies of your input and the local oscillator.
The volume is quite low. You should amplify it a little bit.
Thank you for this sharing

Great video; thanks for posting it. I thought mixer linearity was inversely proportional to diode resistance; hence the need for higher LO drive. So do these high IP3 mixers with their 23 dBm or higher LO requirements actually get you anything, is is it a diminishing return?
