Junior Research Fellow in RF Design: Miniaturised UHF Diplexers at IIT Kharagpur
Job Description
Prof. Mrinal Kanti Mandal in the Department of Electronics and Electrical Communication Engineering at IIT Kharagpur is recruiting a Junior Research Fellow (JRF) for a project on miniaturised diplexers in the UHF band. The post suits a B.Tech graduate in ECE or EE with a GATE score and an interest in RF and microwave hardware. Apply by 24 September 2026.
At a glance
- Position: Junior Research Fellow (1 post), Ref. IIT/SRIC/R/ADU/2026/101
- Project: Miniaturised Diplexers at UHF band
- PI: Prof. Mrinal Kanti Mandal, Electronics and Electrical Communication Engineering
- Upper age limit: 28
- Apply by: 24 September 2026 (online, no fee)
A diplexer splits or combines two frequency bands on a single antenna port, and it is a standard building block in radios. At UHF frequencies the wavelengths are long, so shrinking filters and diplexers without losing performance is a real design challenge.
What the role involves
- Design and development of miniaturised diplexers and related RF filters in the UHF band
- Measurement of fabricated circuits with RF equipment such as spectrum analysers and vector network analysers (VNA)
- Simulation and data handling, where the advertisement asks for Python skills
Eligibility
- A postgraduate degree in basic science, or a graduate or postgraduate degree in a professional course, with selection through a national test (CSIR-UGC NET including lectureship, or GATE) or a national-level exam run by bodies such as DST, DBT, DAE, DOS, DRDO, MoE, ICAR, ICMR, IIT, IISc, IISER or NISER
- Essential criteria in the advertisement: a BE or B.Tech (or equivalent) in Electronics and Communication Engineering, Electrical Engineering or equivalent; knowledge of electromagnetic theory and RF and microwave engineering at the level of the GATE syllabus; and a minimum GATE score (the ad does not state the cut-off)
- Desirable: knowledge of RF filters and antennas, experience handling a spectrum analyser or VNA, and Python programming
- Upper age limit: 28
The advertisement gives no separate details on tenure or the interview process.
Pay and duration
- The pay field in the online advertisement is blank; confirm the fellowship amount with the PI
- Project-linked post
How to apply
Apply online through IIT Kharagpur’s SRIC staff recruitment portal, using the Apply Online button on the official advertisement. The advertisement lists no application fee. Apply before 24 September 2026. Other current SRIC project openings are on the SRIC recruitment page.
Key dates
- Last date to apply: 24 September 2026
Please read the official IIT Kharagpur SRIC advertisement before applying, and browse more JRF positions on ResearchJobs.in.
Hiring institution: Indian Institute of Technology Kharagpur

How to prepare for this application
- Show RF hands-on work: any filter, antenna or matching network you designed in HFSS, CST or ADS, and measured on a VNA, is the strongest evidence you can give.
- Revise the GATE basics: the ad names electromagnetic theory and microwave engineering from the GATE syllabus, so expect questions on transmission lines, S-parameters and resonators.
- Fill the portal form carefully: SRIC screens applications on what you enter, so give exact marks, CGPA and dates, and upload the documents it asks for.
- Check the age limit and relaxations: the upper age limit is stated in the advertisement, and relaxation for reserved categories follows institute norms.
- Contact the PI's group if unsure: faculty email addresses are on IIT Kharagpur's department pages; keep any query short and specific.
About IIT Kharagpur and SRIC
IIT Kharagpur, founded in 1951, was the first of the Indian Institutes of Technology. Its Sponsored Research and Industrial Consultancy (SRIC) unit manages externally funded research projects and recruits the temporary staff, such as JRFs, SRFs, project associates and project assistants, who work on them. These are project-linked posts: they last for the tenure the advertisement gives, or until the project ends.
