Research Assistant at the University of Arkansas

Aug'04 - Dec'06

. Defined RF specifications for a GSM handset receiver front end and

designed an RFIC architecture that meets the specifications in GSM

05.05 version 5.5.1 (ETS 300 910). Using link budget analysis, Agilent

ADS and Spectre RF tools, Blocking characteristics, Intermodulation

characteristics, receiver sensitivity and reference interference level

were determined.

. Performed Frequency and Power planning for CDMA and GSM systems.

. Experience in evaluating the receiver sensitivity through BER, SINAD

options.

. Device testing and evaluation of S-parameters and characterized using

load pull method for large signals.

. Implementation of Microwave scanning of objects and clothing for

Homeland Security System from 8-40GHz.

. Designed a LNA at 5.2 GHz with 100MHz bandwidth, VSWR <2 dB, Gain >5

dB, NF <2 dB and 1 dB Compression >16dBm using LTCC substrate.

. Developed a code for inversion of Brewster angle in Anisotropic left-

handed Metamaterials and development of Inverse algorithm to extract

the material properties.

Training

. Attended 2 day program to enhance presentation skills.

. Attended HFSS training course onsite at Lexmark International.

. Attended GSM overview training course at University of Arkansas.
