About RF Cafe

Kirt Blattenberger - RF Cafe WebmasterCopyright
1996 - 2016
Kirt Blattenberger,

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

Here is an example of a resume that was literally hijacked and posed on a resume board by someone else. In this case, the resume that was hijacked belongs to me, Kirt Blattenberger. The content shown below is exactly as I copied it off of the WirelessDevNet Career Center website. Here is the URL for the resume if you want to see it for yourself. I don't plan to ask for it to be removed just because is serves as such an excellent example. Thanks to Kelly Painter for finding this!

Test Experience
Accordingly, much of my time as an engineer has been spent in a field and military
environment building, tuning and measuring circuits and systems .My borrowed
motto is, "If it hasn't been tested, it doesn't work." No amount of simulation
and planning can suffice to declare a design working without testing over all
planned operational conditions. Test equipment is listed below

Test ?quipment Familarity
Spectrum analyzer, oscilloscope, frequency counter, power meter, SINAD
meter, frequency synthesizer, signal generator, DMM, gain/phase meter,
I/Q test set, logic analyzer, arbitrary waveform , generator, noise figure meter,
analyzer, modulation analyzer, passive intermodulation (PIM) analyzer
(including GPIB interface to many)

Detailed Experience (chronological order, beginning with the most recent):

Designed turn-key production test solutions for wireless base station
and wireless appliance products in the GSM, DCS, PCS and iDEN^(TM) bands.
Generated electrical engineering portion of test system proposals,
including concept definition, cost estimate, labor schedule and customer interface.

Performed passive intermodulation (PIM) testing on high power base
station components.
Supported design and integration effort on VHF radio multi-port cosite
interference cancellation system.
Designed UHF amplifier/filter printed circuit assembly.
Designed and tested VHF switch matrix and amplifier PCA.
Perform system design and analysis on C-, X-, and Ku-Band satellite
earth station systems.
Create production assembly drawings and parts lists.
Specified, designed, analyzed, ordered parts for, directed building of,
documented, tested and integrated RF/analog transmit/receive chain of
Multi-Purpose Airport Radar (MPAR) IR&D project. S-Band through baseband
up/down conversion using combination of coaxial and waveguide components
was accomplished. Interfaces to digital controller circuits included
LVDS, RS-422 and relay implementations. High speed PIN switches and
attenuators; low noise amplifiers; high precision, low noise opamp
circuits; and precision A/D converters were used.
Provided technical support to field engineering effort responsible for
initial testing and verification of active element phased array antenna.
