Professional Experience

Northrop Grumman Chandler, AZ February 2018 to June 2020

Principal Electrical Engineer

RF Product Lead responsible for Transmitters, Low Noise Amplifiers and RF Passives for Launch Vehicles Division, Subsystems group (Missiles and Defense Business unit).

Job duties included working on the specs, supervising and overlooking the design, validation and testing of these mentioned RF Components. Working very closely with the vendors and the supply chain managers, chief engineer and documenting potential issues.

NXP Semiconductors Chandler, AZ

Principal RF Validation Engineer June 2016 to Dec 2017

Responsible for driving and leading Power Amplifiers and Low Noise Amplifiers RF validation in Chandler Site.

Tasks including setting up labs, purchasing equipment, meeting with Vendors, attending and contributing to design reviews, supervising technicians and software automation team, analyzing data and providing feedback to the stake holders.

Leading RF bench validation efforts (data collection, data analysis and bringing solutions for possible issues.

Parameters measured such as NF, Gain,P1db,IP3, S-Parameters, etc…

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…..). Completeness of the test plan identified several significant issues helping avoid a costly board spin and resulting in the successful launch of the products.

Developed full automation scripts using Matlab, TCL and C# that became the standard for validation improving efficiency and consistency. Scripts helped reduce waste in both retesting and engineering time.

Defined and designed RFIC evaluation boards used for characterizing Wi-Fi chips.

Electrical Validation of LVDS type high speed interfaces for mobile devices e.g., PCIexpress

Validate characteristics of high speed interfaces such as PCIe, USB,

Develop new methodologies to improve the silicon validation process

Wrote and modified scripts and ran validation test in the lab

Develop and implement electrical validation for CPU memory interfaces

Validated firmware protocols and interfaces

Debugged and optimized Wi-Fi SV boards.

Worked with instrument suppliers to develop new drivers to meet the demands of validation of PCI X versus the electrical compliance specifications.

Provided engineering support of Cost Reduction analysis evaluating BOM cost of the board.

Texas Instruments, Santa Rosa, CA Jan 2002 to Feb 2005

RF / EMC Engineer

Designed RF, test and prototype boards which helped in characterizing the company’s core business (WLAN chips). Worked with most RF measurements equipment (NA, power meter, spectrum analyzers, network analyzer, and oscilloscope) as well as PCB design tools including OrCAD Capture and Smith chart. Performed all necessary RF Measurements (NF, IP3, P1db )

Established and built complete EMC Compliance measurements Setup system which resulted in significant savings for the company by eliminating visits to the EMC labs.

Increased the speed and efficiency of the EMC test by building and implementing automation tools.

Regularly performed various EMC measurements including FCC & ETSI for IEEE 802.11a, b, g WLAN products (AP, PCI, MiniPCI, Card Bus, USB, and Compact Flash).

Troubleshot EMI problems to ensure required specifications were met resulting in reduction in the number of board’s fabrication spins and elimination of design force investigation time.

Wrote application notes on the EMC setup and measurements resulting in easy information access and training for technicians.

Developed test setup environments (PER test, S/N ratio measurements).

Created and automated an Antenna Evaluation Setup to characterize antennas from external vendors.

Worked with ISO quality process standards in documenting test results in ClearCase and submitting defects in ClearQuest to improve development and process continuously.

Protura Wireless, Half Moon Bay, CA Apr 2001 to Sep 2001

RF Engineer
