Objective
To technically contribute to the design and validation of hardware boards that has scope for innovation
and automation.
Texas Instruments: 2016 Sep to Present
Analog & Mixed signal IC Test engineer.
Qualcomm India: 2015 Dec to 2016 Sep
As a Hardware Application Engineer in the Qualcomm Innovation Lab, my responsibility is to
support the start-up companies develop solutions using Qualcomm chipset under the “Make In
India” initiative. I provide support in the design of the RF front end systems, testing and trouble-
shooting of WTR and RFFE devices, do system board level schematic and layout reviews and BOM
optimization and address queries on the Qualcomm chipsets.
I developed a Visual Basic based RF port mapping tool that helps customers to easily map the RF
bands to the WTR chip ports. Due to WTR chip design limitations not all RF band (HB,MB,LB) can
be mapped to the respective ports of the WTR chip. Earlier by way of two documents the
customer had to assign the correct ports. With the tool that I developed this mapping effort is
drastically reduced to less than 10 minutes. It also has the advantage of avoiding manual errors. I
was given Qualstar award by Qualcomm for this automation.
Astra Microwave Products Ltd.: 2010 to 2015
My role was that of RF Sub-system design engineer. My responsibility was to design & develop the
RF Front end sub-systems for Airborne RADAR applications.
Project : Advanced Quad Channelized Receiver (18-40GHz)
Client : Defense Electronics Research Laboratories.
Description : Channelizes broadband (18-40GHz) into 6 bands then down-converts into
2-6GHz, 750-1250MHz and 140-180MHz.
Accomplishments:
I designed high efficiency power supply using LDO that reduced the power consumption by 22%
from 55W to 43W. Lower power was a key requirement for airborne platforms.
By using the Gain distribution theory with the L-C-H approach I reduced the spurious emission
issue from -30dBc to -40dBc.

2. Project : Extended Dynamic Log Video Amplifier (2-18GHz)
Client : Bharat Electronic Limited.
Description : Converts RF power into the DC voltage levels by maintaining high linearity over
the range of -66 to 0dBm. This Sub-system is used to finding the direction of arrival of the TARGET
based on the received signal strength.
Accomplishments:
EDLVA is operated by +VE and –VE supply. In order to operate the System in safe mode, it is
mandatory to enable -VE supply first and then +VE supply. I designed a sequence enabling circuit
that controls the power supply in the receiver. It Enables –VE supply first and then +VE supply. In
case of absence of –VE supply it automatically shut downs the +VE supply. Earlier 80 out of 100
receivers failed due to the improper supply sequencing. After the implementation of this circuit
there were NO failures in Field.
Due to the design limitation of EDLVA, meeting Accuracy and Linearity specification was a tough
challenge. I came up with an idea to improve the design to meet high accuracy specification by
utilizing the curve transfer techniques to linearize the curve. This design approach requires
complex mathematical analysis so I developed a tool called CADAT (Computerized Advanced DLVA
Designing and Tuning). This tool can design the ADLVA circuit based on the requirement given by
the user. With this tool the design cycle time reduced from 1 day to 1 hour. The accuracy achieved
by this tool was 50% better than the state of art solutions available at that time. This tool won the
1st
place in the Astra Idea Hackathon event. Due to the project priorities this idea was not
implemented in the hardware.
Project : Coarse Direction Finding Receiver (0.4 – 18GHz).
Client : Defense Electronics Research Laboratories.
Description : Converts RF power into the DC voltage levels by maintaining high linearity over the range
of 0.4 – 18 GHz and -60 to 0dBm power. This Sub-system is used to finding the direction of arrival of the
TARGET based on the received signal strength.
Accomplishments:
This receiver system consists of inbuilt LO for BITE option. User can operate the device in two
modes i.e., External RF I/P mode and Internal LO mode by controlling the RF switch. Due to
leakage and poor isolation of the RF switch the LO signal coupled to output when the user
operated the device in External RF I/P mode. I came up with an idea to control the power supply
of the LO with the switch control. In case of RF I/P mode Switch control is ‘1’ and this makes the
LO Power supply off and hence no leakage.
3. Project : Threshold detector (7.5 – 18 GHz)
Client : BEL
Description : Triggers when the received signal power reaches the threshold value set by the user.
Accomplishments:
One of the time consuming activity was the design tuning process which involved lots of
calculations and analysis. I developed EXCEL template that automated the design tuning process
and reduced the tuning time.
Project : Phase Measurement unit (750 – 1250 MHz)
Client : DLRL
Description : Measures the phase differences between two signals received from the antenna, and
provides the IQ as output.
Accomplishments:
