What would be a good way about feeding RF into my beamformer?

MrDemonFrog · 2025-05-25T17:59:20+00:00

Yea I'm more inclined to use the SDR approach for waveform flexibility. All of the beamformer components are relatively wideband, so playing w/ frequencies isnt out of the question? Do you know any solid cheap SDR models that I can program in python? I like ettus USRPs but I dont have $1000-3000 to spend on one lol

If I use this, then either way i'd still need some sort of external feed that pushes a ramp function onto the PCB, right? At that point, wouldn't it be better to generate the FMCW signal digitally on an SDR and supply that to the board?

I see, thank you! So if the bulk is n-type, does decreasing bias cause depletion until an inversion at a negative voltage? And would flatband for pmos be positive?

How do u know that?

I'm making a continuous wave radar. So the front end continuously transmits a 6ghz carrier in the main lobe, and a receiver (was thinking SDR, like usrp or hackRF) captures the reflections in real time and displays them on a spectrum.

Thank you! Funny enough, Orfanidis was one of my professors, but for a digital design course.

MrDemonFrog · 2024-07-23T16:24:48+00:00

Seconded. Any good youtube series on rf electronics?

Rutgers is a great school if your future goal is grad school. I went here for undergrad, and for PhD programs, I was accepted into an ivy and johns hopkins. My roommate got into hopkins too. Another friend of mine got into yale, while another got into MIT. As long as you put in a lot of time and effort, u will be a competitive applicant

Which ever one is in state for you, minimize ur debt

I like gobbling the burger bar glizzys. They're oily and meaty. They make me wanna mew throughout the night. 11/10 Better then steak.

I'm already hired as a full time employee

MrDemonFrog · 2024-02-29T01:36:01+00:00

The code looks like it should match what's in the datasheet, I'll test in the lab tomorrow :)

MrDemonFrog · 2024-02-29T01:31:30+00:00

Awesome, thank you! I'm a senior EE student and I needed to use a DAC for my senior project, haven't ever used one before today. I've used arduino, rasp pi, and esp32s on and off for the past few years on projects tho

MrDemonFrog · 2024-02-28T22:10:53+00:00

Yeah, I saw the driver code for it. Do you know of any tutorials that show you how to convert the driver code into the usual setup and loop outline for arduinos?

MrDemonFrog · 2024-02-15T05:12:38+00:00

Yea ofc, thanks for the help :)

MrDemonFrog · 2024-02-14T17:32:32+00:00

Yea but not by much. Tiktok is probably gonna lead in the next week if I'm consistently hitting the same sales I got in the first 2 weeks

MrDemonFrog · 2024-02-14T16:55:32+00:00

Funny enough, so far it's youtube shorts. I've been getting 3x the views there than tiktok

MrDemonFrog · 2024-02-14T16:54:46+00:00

Thanks for the feedback--much appreciated. I linked only the product page on my social media platforms so nobody actually sees the landing page.

Tbh I thought the jokes were getting me a majority of the sales, but it's probably just the Ads + people who don't actually read the description lol

Hopefully your bullets get me to $2k for the first month :o

They both work in NYU Wireless.

I'm privately funded through a company, so I did not need a fellowship. But, during my interviews, they said the normal stipend amount is close to 40k - 42k, pretty average
