Design of RF transceiver design for 802.11b, Zig-Bee, Bluetooth using Agilent ADS June-July 2019

Transceiver operates at 2.4GHz with data rates up to 1.0Mbit/s with QPSK modulation.

Exhibited a noise figure of 4.2 dB (transmitter side) & 4.225 dB (receiver side). The error vector magnitude

(EVM) is 9.7% and receiver sensitivity is -95dBm

Design, fabricate, and test a -18 dB maximum-flat 7-stage directional coupler Jan-May 2018 Technologies used: AWR, ADS, Circuit Pro, Network Analyzer

Derived design calculations (even and odd mode analysis, coupling) and line calculation using ADS

Tested, fabricated and tuned (reflection co-efficient, S11=0) the design using S-parameter files for optimal performance in operating modes using network analyzer

Design of quarter-wave transformer at 2 GHZ using AWR Mar 2018

Designed a quarter wave transformer for 100 ohm transmission line to match real impedance of 200 ohm

Extended to multi-section designs to provide a broader bandwidth and verified using rectangular graph

Design of 4G Wireless Receivers with Cascaded Double sampling Sigma-Delta Modulator Sep 2016

Increased OSR (over sample ratio) over a wide bandwidth range using double sampling technique

Modeled and analyzed modulator performance in MATLAB for GSM, CDMA, Bluetooth, GPS

Path planning strategy and detection of intruder in VANET using real time transportation system http://www.iraj.in/journal/journal_file/journal_pdf/12-265-146831871182-85.pdf Nov 2015-Apr 2016

Used path planning algorithm to avoid congestion of vehicles in an urban area by optimally balancing the overall network smoothness with drivers’ preferences by prioritizing emergency vehicles in a network by a master key

Microwave Amplifier and Low noise GaAs amplifier(LNA) design theory and principle June 2018

Designed a low-noise GaAs MESFET amplifier at 4GHz with given S-parameters for stability and gain

Designed using ADS & calculated the values of K, Δ (delta) to check the stability of device and derived the parameters like noise figure (NF), center and radius of NF circle (CN, RN) and gain circle (CG, RG) EXTRACURRICULAR/ LEADERSHIP ACTIVITIES Aug 2017- Present
