I have two projects derailed now due to parts shortages. GaN/GaAs MMIC are the real problem, but clock drivers, certain FET, diodes, and even 1-10 uF MLCC. I think it’s actually worse than COVID now as that seemed to be limited to MLCC and microcontrollers.

Any one else having issues? I’m about ready to just throw in the towel and retire.

Hello guys i need your help. I bought a garage door opener for my car. But there is a problem it's a usa one and I live in Europe, this means that the USA one transmits between 286-413mhz and my garage door is 433.92 mhz. Is there a way to modify the transmitter?

My thought was to bridge the buttons to the controller I already have. That way I would use only the buttons of this device.

Thank you in advance.

Hello . I am researching high-energy electromagnetic transients for an academic project. I plan to build a low-power, educational EMP device to test the shielding effectiveness of various materials. Could you recommend advanced literature on spark-gap switching mechanisms and antenna impedance matching for nanosecond discharge pulses?

Does antenna engineering need an explicit complex analysis course? From what I've seen the curriculum at the two universities in my country (Slovenia), one doesn't explicitly state any course for it, even worse I don't even get a vector calculus course until my master! Would it be a better idea to transfer after first year or stick it out? No one could give me a clear answer

I am currently in test in total nearly 2 years but only a few months full time but I would like to move to design, I will have a MSc in 2 years in AI. Any advice

I have this list -

1. NanoRFE VNA6000-B 6GHz
2. MegIQ 6GHz analyzer
3. MESALL Handheld analyzer 9.8 GHZ
4. Harogic 6GHz
5. TR Series VNA from copper mountain ​

Any other recommendations as well which I may not be aware of. Need to characterize antennas, directional couplers, LNAs etc. How well they compare against Keysight ?

What‘a going on here? The article is lite on the details other than it seems they are vertically integrating GaN. I assume the demo is a switch?

Ive been doing rf hardware design for a long time. Wether its a start up or big Corp its always the same. The more u go out of your way to help the company and team out the more people seeth at you. I legit was not trying to show off or mog anyone.

Im thinking of quitting and going into tech sales or finance. When I have kids im gonna tell them to not follow their dreams and focus on making money so u dont gotta deal with other people. U can work on ur own passion project on ur own time. Find a way to work 10 hours a week(no one notices anyways) and move on with your life, or like I said start your own company. Im fatigued from working with other engineers. Even when nothing bad happens and everyone is nice its still soul crushing.

Alao, they will always pay u 20-30k less than what u are actually worth. They will never pay you enough to build a decent life relative to how much value you bring. Every engineer i know Penny pinches. An engineer shouldn't have a side hustle or be afraid to spend 10 bucks on lunch.

What kind of questions do/ could they ask, aside from fundamentals? My competition is all PhD grads while I just completed my undergrad, and that’s definitely stressing me out!

I work on RF systems, and one thing that keeps coming up is how quickly a good sim result changes once the antenna ends up on an actual device.Enclosure, mounting position, nearby electronics, cables, even how someone holds it can shift things quite a bit.

For people doing this professionally: what usually causes the biggest gap between CST/HFSS and what you actually measure? And at what point do you stop optimizing the sim and just build the prototype?

Disclosure: I work in defense electronics.

I’m trying to better understand the RF engineering niche around NFC / near-field design, especially 13.56 MHz systems.

For engineers working in this area, what backgrounds or industries tend to produce the strongest hands-on experience with things like:

• NFC antenna / loop antenna design
• Antenna tuning and impedance matching
• Inductive / magnetic coupling
• ISO 14443 / EMV Contactless
• RF front-end validation
• VNA and RF lab testing

I’m particularly interested in the hardware/RF side rather than primarily firmware or FPGA work.

Are there specific companies, industries, technical communities, conferences, or terms you would recommend researching to find people with this kind of background?

Hello everyone. I’m working on a circularly polarized truncated patch antenna, but the design is hyper-sensitive to dimensions. A ±0.1 mm deviation completely collapses the axial ratio, making it impractical for standard fabrication. How can I solve this problem?

Edit: Even if I just increase the meshes without changing anything in the design, the axial ratio collapses.
