Résumé du poste

Thinkpalm Technologies is seeking an experienced RF engineer to design and simulate RF front-end parts and integrate SDR transceivers into complex systems in Kerala, India. The role covers budgets, propagation modeling, and collaboration with SDR and networking teams.

The candidate should have a degree in Electronics & Communications, hands-on RF project experience, and proficiency with Keysight ADS, MATLAB, Simulink, and GNU Radio. The position is on-site in Kerala.

Qualifications

• Degree in Electronics and Communications Engineering or MTech in Microwave engineering.
• Hands-on RF engineering with at least one transceiver integration project.
• Working proficiency in Keysight ADS for RF budget, S-parameters, filtering.
• Strong grounding in link budgets, noise figure, linearity and impedance matching.
• Experience with spectrum analysers, VNAs, signal generators and power meters.
• Experience with at least one RF propagation tool and terrain models.
• MATLAB scripting for test automation and Simulink experience.
• Understanding of OFDM/PSK/QAM, SNR, EVM, BER/PER.

Responsabilités

• Design and simulate RF front-end parts (amplifiers, filters, matching).
• Integrate SDR transceivers (AD9361/AD9363) into the system for band selection and TX power.
• Build and calibrate an RF test bed for 8+ radios with documented power budgets.
• Model links between sites over terrain and produce budgets and maps.
• Collaborate with GNU Radio/SDR and networking engineers to set modem bandwidth and diagnose link issues.

Description du poste

Key responsibilities

• Design and simulate RF front-end parts (amplifiers, filters, splitters, matching networks) in Keysight ADS, and specify off-the-shelf components.
  Integrate SDR transceivers (AD9361/AD9363-class, such as the AntSDR E200) into the system: band selection, gain staging, TX power, filtering and clock references.
• Build and calibrate a conducted RF test bed for 8+ radios: attenuator matrix, splitters, fixed pads, shielding and cabling, with documented power budgets and receiver protection.
• Model links between sites over terrain with propagation software (SPLAT!, Radio Mobile, MATLAB RF Propagation or commercial tools), and produce link budgets and coverage maps.
• Convert terrain path loss and node movement into attenuation settings and emulator link quality, so scenarios (relay loss, jamming, out of line of sight, partition and merge) can be replayed on demand.
• Work with the GNU Radio/SDR and networking engineers to set modem bandwidth, data rate and margins, and to diagnose link problems with a spectrum analyser and captured IQ data.

Required qualifications

• Degree in Electronics and Communications Engineering, or M Tech in Microwave engineering or equivalent.
• Hands-on RF engineering, with at least one transceiver or radio integration project.
• Working proficiency in Keysight ADS (RF chain budget, S-parameter analysis, matching and filter design).
• Strong grounding in link budgets, noise figure, linearity, impedance matching and RF measurements.
• Practical use of spectrum analysers, vector network analysers, signal generators and power meters.
• Experience with at least one RF propagation tool and terrain models (Longley-Rice/ITM or ITU-R methods).
• Scripting in MATLAB for test automation and experience in Simulink.
  Understanding of digital modulation (OFDM, PSK/QAM, GMSK), SNR, EVM and BER/PER.

Nice to have

• Experience with SDR platforms (Analog Devices AD936x, USRP, Pluto, Zynq-based radios), GNU Radio, UHD or libiio.
• Programmable attenuators or attenuator matrices (Mini-Circuits, JFW, Adaura, Vaunix) and RF channel emulators.
• Tactical radio, VHF/UHF or defence communications background; awareness of frequency hopping and electronic warfare.
• Keysight SystemVue, MATLAB Communications or Antenna Toolbox.
  EMC testing and spectrum regulatory work.Familiarity with network emulation (Mininet-WiFi, EMANE) or mesh networking
