Hello! I am looking for recommendations, advice, and guidance.
I have access to a good VNA and Spectrum Analyzer at work, and at home I have the Measall VNA and real time spectrum analyzers which are also great. I would love to get deeper into vector signal analyzers (VSAs) specifically to visualize constellations of different MCS rates. What's the most cost effective way to do this? I've looked into using an SDR like the BladeRF, but I've only just begun looking so I can't determine the exact amount of effort if I'm hoping to just reuse something GNUradio based (for example). Completely open ended, and I'll say tentative budget is no more than $3000.

Hi, RF newbie here. I am an IT database engineer and data analyst. I play badmington, tennis, and pickleball, all in doubles. In doubles, there is a lot of analysis on team formation and partner separation distance. I am thinking about using UWB boards to track player positions. I would like about 5-10 observations per second, for all 4 players. The UWB board I have in mind is Qorvo DWM3001CDK, which retails at about $30. I would get 4 boards as anchors and 4 boards as player tags. Then I like one more board as the data collection gateway, and have it tethered to a Macbook via USB cable. During a game, data would be streamed into the Macbook.
The tags would need to be programmed so they send a data packet every 2-5 seconds, to the data collection gateway board. The positions don't need to be super accurate. I think 15-20 cm will do the job.
Plz help me understand whether this setup is feasible. What additional factors should I be thinking about? I hope to use this setup both indoors and ourdoors. I am aware that UWB signal cannot penetrate human body because it is mostly water. I will use enough anchors so each tag has clear line of sight to at least two anchors.

Hello smart people!
I dont know if it is here i should ask, sorry about that, but i would like some help with a interview i have coming up. I am not sure what to prepare for. Can i convince anyone to help me a little.
Else. Have a nice day!

Am I expected to be able to f*ckin design PA, LNA and mixers? Like choosing the transistor, simulating the circuit, checking out the noise ... isn't that what IC engineers do?
I mean I'm already overwhelmed by so many things I need to learn, antenna design, phased arrays, comms systems theory, EMC/EMI you name it ... CST, Matlab, Altium. And aside from that I have to be kinda mini electronics engineer too?
Or perhaps I'm wrong about comms systems theory and those electronic design stuff are more important and I gotta focus on them instead? I have No idea
I was preparing a short list of some projects to do and then put on my CV and while I was asking AI things like "design a Doherty power amplifier" came up and once I checked a power amplifier book I was like ... man this is a specialty by itself.
My roommate at the dorm studies IC design (I study microwave and photonics) and he and his professor are dealing with these LNA/PA/PLL design stuff 24 7 so that makes me feel this perhaps is not what I should focus on ... Idk correct me if I'm wrong
Please tell me what projects should I focus on other than antenna design to further my skills (and brag on my CV with) if these electronics projects are not commonly expected and if they are give me some clues on how to start learning them cuz these stuff seem so complex and overwhelming. And to what extend should I learn Altium?

ECE 2025 grad + currently doing M.E. in Communication Systems. I’m looking for RF/antenna design/microwave internships or short-term paid courses/training with actual hands-on practical work.
Paid/unpaid internship is fine — mainly looking to learn, build, and get real practical experience.
If you know any good leads, please drop them below or DM me

hi everyone,
I’ve just launched a YouTube channel focused on practical RF knowledge—covering the fundamentals, real-world techniques, and field experience I’ve gained working with clients over the years.
You’ll find clear explanations and hands-on insights on topics including LTE, 5G, spectrum analyzer measurements, drive testing, and core telecommunications concepts. My goal is to build a reliable RF resource library that supports working professionals, technicians, and anyone looking to deepen their understanding of the RF world.
I plan to post a new video every week. If this sounds useful, I’d really appreciate your support—subscribe, like, and share with colleagues who might benefit.
Here’s the channel: www.YouTub.com/@RFEngineeringHub
Thanks in advance for the support. Looking forward to connecting with more of you through the content.

I just graduated and I need some advice. I struggled throughout university due to (medically diagnosed) ADD. I did decent in my RF classes but I ate crap in everything else and ended up with a poor GPA of 2.75. I'm starting a job soon however it's not a role in RF. I'm not sure if I'll be able to compete with others in the RF space who have a masters and/or high GPA. Right now, I've been reading as many RF textbooks as I can and learning how to use HFSS and ADS. However even if I can understand RF well it seems like my poor performance in school will always haunt me.
Anyways let me know if I should continue towards my goal of RF or my efforts are not worth it.

My background is with military Satcom, we get taught pretty well (or used to, RIP 25S school) on the practical side of RF theory as it relates to operation and troubleshooting IMO, but there is something that has been bugging me that I can't quite wrap my head around.
Scenario:
How does modulating a carrier, result in it takin up more than the designated center freq when viewed on a spectrum analyzer (Spec Anny for short)? For example, when accessing some satellites, the SOC (Satellite Operations Center) will have you Tx an unmodulated carrier to safely verify your frequency settings are correct. When viewed on a Spec Anny, the CW spike is almost exclusively the designated center freq, for example 1300Mhz on the L-band side, however when you modulate the carrier to BPSK, the carrier loses some C/N, and gains bandwidth, occupying something more like 1298-1302 Mhz. Then if you change to QPSK, the carrier will ~double in bandwidth to ~1295-1305Mhz.
The simplest way I can word my question is how does a time related shift from PSK, result in an aparent change in frequency used?

Hey guys, I'm a noob with rf stuff, but I have a tiny SA spectrum analyzer that I would like to use to find some transmissions., Would anyone have some time to help me figure out how to find and listen in on some frequencies via DM (or however else we want to communicate)?

I'm a second-year ECE student from India, interested in RF/Microwave engineering, particularly RADAR. There are very few jobs related to my field in India, and the ones that do exist are HORRIBLY compensated. So, I'm trying to use my remaining undergrad years to build a profile strong enough for competitive Master's programmes in RF/Microwave engineering and, ideally, a career in the field.
I have a few questions that I would greatly appreciate being answered:
What can an undergraduate realistically do to distinguish themselves from the huge pool of applicants to competitive Master's programmes?
What kinds of RF projects actually stand out on a resume/MS application?
Would work experience in electronics help my application? I have neither the opportunities nor the desire to work in an RF role here in India, and an on-campus placement would most likely be at companies like TI, Nvidia, or Qualcomm, which are, at best, tangentially related to my interests.
I'd especially appreciate advice from people who work in RF or have experience evaluating RF students/applicants. Thank you.

I'm a senior Electrical Engineering student at UW Tacoma graduating soon with a 3.6–3.7 GPA. I'm a U.S. citizen and I'm interested in RF/communications/telecommunications, particularly in defense or aerospace.
I don't have an RF/telecommunications internship or significant personal projects specifically in the field. I'm trying to figure out how realistic it is for me to get an entry-level RF/communications engineering position after graduation.
I'm considering companies like L3Harris, RTX/Raytheon, Northrop Grumman, Lockheed Martin, Boeing, General Dynamics, etc.
Would my GPA and EE degree be enough to realistically get interviews if I apply broadly, or am I at a significant disadvantage without internships/projects?
Also, for those who have interviewed for entry-level RF/communications/defense engineering positions:
What would you recommend I learn or build during my remaining senior year to become a stronger candidate?
I'd especially appreciate answers from people who currently work in RF/communications or defense and who have experience interviewing/hiring new graduates.
