Validation/Characterization Engineer

Location: Bengaluru, Karnataka, India

Texas Instruments RF Connectivity group is expanding their RF Transceiver Validation Group in Bangalore, India.
This group develops cutting edge RF Transceiver products (+MCU integrated) for Wireless-LAN (WIFI) and Ultra-Wideband Systems (UWB).
The RF Validation group primarily focusses on the following aspects:

1.  Debug of The Transceiver SoC: Fast and Systematic Identification of the issues in the blocks. Observe and identify the root cause. Drive solutions and not just report problems. The debug would involve either Power & Biasing issues, Incorrect register sequence or incorrect values, Board level issues etc.
2.  RF Measurements: Understanding of each RF, IF and DC measurement. Example in Receiver chain, measurement of Noise Figure & Gain of the chain, Linearity measurements such as P1dB, IIP2, IIP3, IQ gain & Phase error, LO Leakage and DC offsets. DC operating point measurement via Test Mode, DC Voltages and Current Consumption. Similar measurements for TX chain, PLL, Reference Clock.
3. PCB Board Development: Development of PCB Schematic and Layout, PCB material selection, stackup, review the design and implement the changes. Working with 3rd party PCB service companies. Familiarity with Altium and Cadence Allegro flows.
4. Test Automation and Interpretation of Measurements: Person is expected to have proficiency in Coding & Automation of the measurement flows including interfacing of instruments. Processing of the measured data across PVT corners, Visualization, and ability to identify between IC and setup issues. Basic understanding of statistics and sources
5. Interfaces: Ability to deign and program interfaces such as SPI, UART, UCI.
