Intel Corp., Hillsboro, OR & Chandler, AZ July 2005 to May 2016
Sr. RF / Post Silicon Validation Engineer
Responsible for validating Intel based smartphones, tasks included all aspects such as validating Wi-Fi, 3G, LTE and GPS circuits.
Built an SV (Silicon Validation) test setup and generated complete test plans for Wi-Fi (802.11) test chips
Validated RF ports related to Bluetooth and NFC.
Developed and executed the complete post silicon validation RF measurements for 802.11 chips (P1db, IP3, Harmonics, Gain Flatness, LO Leakage, etc…..).
