Mtech in RF and Microwave at IIT Kanpur has excellent placement scenarios with a placement percentage of 100%.
The Electrical Engineering department of IIT Kanpur is second only to the CS department and offers the best job opportunities. Irrespective of your branch, you are likely to get placed in a good company with a decent package.
Talking specifically about RF, students receive offers from highly reputed semiconductor companies in India like Intel, Qualcomm, STMicroelectronics, Samsung Semiconductor, etc. Additionally, there are many other recruiters like General Electric, Siemens, Boeing
Securing a core job, however, might be a bit difficult but not completely impossible. Some companies that offer core jobs are Texas Instruments, Qualcomm, Siemens, etc. Usually, the average CTC is in the range of INR 13–15 LPA. The majority of the batch received packages above 15 LPA.
Unlike the general opinion that VLSI is the best branch, I would conclude that RF is one of the best branches provided that you have a genuine interest in it.
