Job Description
Scope:
- In-Line test station SW integration :
- Development of features and maintenance for test stations used for Calibration and Validation of RF technologies.
- SW development and contribution to existing MacOS Application.
- Manufacturing Build support : Support station bring up and execution during Manufacturing build events at CM sites in India
Skill Set:
- SW development experience with Objective-C or similar programming language.
- Understanding of RF measurement parameters specifically around antenna measurements. For example: VSWR, S-Parameters, TRP, etc. - VSWR, S-Parameters, and TRP are key RF/microwave metrics. describe signal efficiency and performance, but from different perspectives: VSWR for line matching, S-parameters for network characterization, and TRP for overall antenna output.
- VSWR (Voltage Standing Wave Ratio) measures impedance mismatch (how much power reflects, 1:1 is perfect)
- S-Parameters (Scattering Parameters) map power flow in multi-port networks (like S11 for reflections)
- TRP (Total Radiated Power) quantifies total transmitted power from an antenna system, crucial for mobile device performance.
