Note: This is in no way an official
resume. This is more like a Pseudo-Resume (kind of like pseudo-code).
It seemed like a good idea to put this out there just as a basic
description of what my job entails (or has entailed in the past).
I'm not currently in the market for employment, but then of couse I am
a practical person.
Objective: I need to think about this a
little bit more... for the time being all I really have to say is that
I am very much enjoying my career in the RF Communications field, more
specifically RF Circuit Design, and hope to keep doing it for a while
longer. I'm a pretty well motivated individual, as long as the
project does not get mired in politics, with somewhat decent
inter-personal skills. I like the idea of working on things that are
new and innovative as well as possibly somewhat "cutting edge". So
far I have only really grazed a small portion of what RF engineering
has to offer, but am loving every minute of it.
Work Experience
-
Microwave Data Systems, Inc
Formerly known as MDS, a division of Adaptive Broadband Corp.
Formerly know as Microwave Data System a division of California Microwave
- Principal Engineer (March 2005 - Present)
- Senior Development Engineer, RF Design (December 1999 - March 2005)
- Development Engineer, RF Desing (December 1997 - December 1999)
- December 1997 - Present: This really needs to be formalized
a little bit more than it is, but for the time being I'll list some of
the projects that I have been involved in and some of the things that
I have done.
So far my design/project responsibilities have been pretty much on a
point-to-point based radio architecture (see the LEDR family of
products on
http://www.microwavedata.com/telecom.asp for some examples). On
these projects I have had involvement with the following:
- Stripline (and microstrip) filters, couplers, matching networks
- Lumped filter design
responsabilities
- 1W GaAs FET linear (strong class A) power amplifier design for
16/32QAM point to point radio systems primarity for 400MHz, but also at
900MHz, 1.4GHz, and 2.4GHz
- Intial systems specifications and topography analysis for a ~2GHz
point to point data link. Considerations of filters, mixers, buffer
amplifiers, NF and system gain requirements were included in this.
- PCB board layout of RF sections for 400, 900, and 1400MHz
- Wrote an automated mask measurement utility (FCC and ETSI) in LABview
to facilitate the measurements on an HP and R&S spectrum analyzer
- Manufacturing training on debug/trouble shooting of our current QAM
point to point radio products
- Involvement with the ETSI, FCC, and Canadian certification of our QAM
point to point radio products at 1400, 900, and 400MHz respectively.
- Some other stuff that I am sure I have forgotten
As of late I have been tasked with work on a 900MHz ISM band frequency
hopping radio. This is a whole new ball game for me and I am looking
forward to the challanges and differences in Point-Multi-Point versus
Point-Point architectures.
I also have knowledge of the following tools: HP EEsof Series IV,
MathCAD, SysCalc, Sonnet EM simulator, basic LABview programming. I'm
also slowly getting some experience under my belt using Eagleware's
Genesys RF modeling tools.
Additionally, I am pretty comfortable around most RF test equipment including
Spectrum and Network Analyzers.
-
Digital Equipment Corporation
(now COMPAQ)
- Hardware design engineer
- Network Products Business Unit, Littleton, MA
- November 1996 - December 1997: Involved in the design/debug
of a dual Primary Rate ISDN (PRI) access router
(RouteAbout Central
EP) option card in a twin-ethernet (2x10Mbit) to 4xE1/T1
(traditional WAN) + 2 PRI router.
Primary responsibilities included:
- the initial system consideration, block diagram and circuit design
- schematic entry and supervision of the layout process
- debug of the sub-systems and final verification testing
- support of the telecommunications certification process
- training of the manufacturing personel at the assembly line in
Ayr, Scottland, in the debug/troubleshooting of the board during the
manufacturing process
Key areas of contribution were to the design/implementation of
PRI (both E1 and T1) line interface portion of the board as well as
the interfacing of a hardware based STAC compression engine to the
system. Assisted with the integration of the DMA based data engine
(Siemens MUNICH32) into the existent Motorola (MC68040 with dual MC68360
slaves) architecture.
- July 1995 - November 1996: Worked on the final debug and
qualification process for a
single ethernet to 1xE1/T1 (traditional
WAN) and ISDN (BRI - 2B+D) access router.
Primary responsibilities included:
- debug and trouble shooting of the embedded micro-controller (MC68360) and
associated transceiver sub-systems
- assistance in the creation and implementation of an ITU compliant
test process for certification with the BABT telecommunication
regulatory body in the United Kingdom
Education:
- B.S. ELECTRICAL ENGINEERING (1995) from
Rensselaer Polytechnic Institute, Troy, NY
- Short courses:
- "RF Design Techniques II" - Besser Associates
- "RF Principles and Practice" - Georgia Tech
- Other:
Non-work Interests:, model trains (N-scale),
amateur radio (K2JJB), tinkering with electronics, automotive repair,
skeet and target shooting, hiking (though not so much anymore)
Additional Information:
- knowledgeable of, and pretty comfortable with, the HP/EEsof
RF design suite (series IV)
- working knowledge of Sonnet electro-magnetic simulator
- fluent in Spanish
- some experience with Digital UNIX, ULTRIX, Windows NT 3.51/4,
Windows 3.x, and Linux operating systems
- very comfortable with the Windows 95/98 operating system and associated
products (MS Office, etc)
- familiarity with PERL scripting language and HTML
- knowledgeable in basic computer networking skills
