August 2000- March 2001 At Indian Space Research Organization

Scientist/Engineer 'SC' in the Microwave Communication division.

Worked on two projects

. Designing the frequency synthesis by the concept of Phase Lock Loop

technique. Simulation is being done by using Matlab

. Designing of the linear MMIC amplifier in the S band (freq-1.5Ghz to

2.5Ghz).using software's - Eesof's Libra, Microwave 2000, MIMP

(Motorola's impedance matching program), LINMIC.

Industrial Training:

Bharat Electronics Ltd. (Duration: 2 months)

. Hands on training on various microwave equipment like spectrum analyzer,

vector network analyzer, scalar analyzer and noise figure meter.

Fabrication tools like dicer machine, laser cutting machine and line

width measurement machine.

. Theoretical Design of directional coupler (one of the passive Component

in the microwave).

Himachal Futuristic Communications limited: (Duration 6 month)

. Designed and fabricated a 2-Stage low noise amplifier at the extended Ku

band (frequency - 17.7GHz to 19.7GHz) for use in SDH radio.

. Software used for simulation was Eesof's Touchstone and Eagleware's

Genesis.

. Work involved selection of active device, designing of the matching

network, designing of the bias supply, simulation, drawing of the layout,

fabrication of the component, drawing the layout of the housing box and

finally the measurement.

Other projects: (as part of course curriculum)

. Simulation of many passive microwave components viz. power divider (both

two way equal and unequal and four way), filter designs (low pass and

high pass filters, bandpass and bandstop, harmonic filter), rat race,

hybrid.

. Completed a theoretical project, for designing the four way unequal power

divider in the C band (freq-3Ghz) using the Microstrip transmission line.

The software was written in C-language for derivation of impedance of

line. Simulation was done using JADMIC and Eesof's Touchstone software's.
