Work with RF transceivers, RF modules, amplifiers, filters, antennas, connectors, and RF front-end circuits.
Configure and test wireless technologies such as LoRa/LoRaWAN, BLE, Wi-Fi, Sub-GHz, ISM-band, and other RF communication systems.
Perform RF link testing, range testing, sensitivity testing, transmit-power measurements, and communication reliability testing.
Analyze RF performance including TX power, RX sensitivity, frequency stability, bandwidth, RSSI, SNR, and link budget.
Perform antenna selection, integration, matching, and RF performance validation.
Troubleshoot RF communication failures at the module, PCB, antenna, and system levels.
Perform RF measurements using equipment such as spectrum analyzer, signal generator, oscilloscope, power meter, VNA, and RF test equipment.
Analyze RF schematics and PCB layouts for proper RF routing, grounding, impedance control, shielding, and component placement.
Work with RF transmission lines and controlled-impedance PCB traces.
Support RF matching-network design and tuning.
Perform RF testing in both laboratory and field environments.
Conduct range and line-of-sight testing for wireless systems.
Investigate interference, noise, signal degradation, and communication dropouts.
Perform RF validation and prepare test procedures, test reports, and technical documentation.
Collaborate with embedded firmware engineers for RF driver, transceiver configuration, register-level settings, and communication testing.
Support hardware bring-up and integration of RF modules with MCUs and embedded systems.
Review RF-related schematics, PCB layouts, datasheets, application notes, and reference designs.
Support EMI/EMC testing and RF regulatory compliance.
Work with PCB and hardware teams to improve RF performance and resolve design issues.
