Past Work

Key fob, short range communications, wireless communications, saw transmitters, Silicon Labs, EZRadio, Si4010, Si4355 development

Over the last 32 plus years, Aerospace Consulting has performed many types of work for many types and sizes of organizations. But, to summarize some of the more significant work, we have created the following list. This list is only representative of some of the work performed by Aerospace Consulting LLC. If you or your company needs rf circuit design and development, prototype design, simulation, RF layout using Altium Designer and PCAD, or troubleshooting on virtually any electronic circuit or system, Aerospace Consulting can help you. And, your project does not have to be huge; anything from a few hours to many months is considered. And, not only can Aerospace Consulting help you with your product design, but if you do not have your own manufacturing capabilities, Aerospace Consulting can hook you up with contract manufacturers who can take over once the initial prototype design is completed. Aerospace Consulting is a prototype company that can take your idea from concept through pre-production.

 

Some of the prototype design and RF, microwave, and wireless design services that we have performed include:

 

Microstrip patch antenna and patch array design and development

 

High power pulse amplifiers for DME and TACAN

 

Load pull measurements for high power amplifiers

 

High power jammer design and development for military as well as Visual

       Basic test software to test that jammer

 

Active GPS jammer remediation system including antenna array and

       nulling circuitry -- including development of the necessary

       embedded software

 

Transmitter design, receiver design, and rf layout for an invention design

       licensed by a client for body scanning system (similar to what is used

       at airports for weapon screening)

 

Unique antenna design for long range (100 meter plus) Bluetooth circuit

 

Assisted client develop high power, low frequency amplifier for medical market

 

Assisted client with design and development of miniature 5 watt telemetry

       transmitter using Feher QPSK. (Very similar to O-QPSK) Article

       written on project with permission of client was cover story for  the

       September 2003 issue of RF Design, now Mobile Dev & Design

 

Downconverter for digital receiver

 

Broadband, fast scanning receiver

 

 LC filter design for many transmitter design and receiver design projects

        from 1 to 1000 MHz

 

Development of low cost, ultra-broadband amplifiers covering up to 26.5

       GHz

 

Microwave filter design and development from 1.5 GHz through over 12

       GHz

 

Various low-pass filter designs from a few MHz to many GHz

 

Range improvement for control of robotic system

 

Helped clients resolve various problems with amplifiers that oscillated

 

Ultra-small, low power transmitters and beacons for item location using

       SAW technology

 

Various short range Bluetooth circuit applications

 

Various low phase noise synthesizers from 100 MHz through over 3 GHz

 

Extensive frequency planning and detailed system simulation for

       transmitter design and receiver design

 

Range improvement on various key fob and similar short range

        communications projects

 

Microstrip patch antenna and antenna array for various applications

        from 900 MHz to over 8 GHz

 

Unique microstrip patch antenna array for producing both null and

        broadside patterns for avionics testing

 

Key member of a team of consultants helping an aerospace company

       develop a proposal for a new UHF digital radio system for the US

       military

 

Designed new amplifier for aerospace company to replace high power

       amplifier module. The new module was needed because the old

       power transistors were no longer available. The really interesting

       part of this  design was that the gain, and phase, response of the

       new amplifier had to be identical to that of the old amplifier.

 

Performed technology research for a large aerospace company to help

       them determine whether a particular technology was worth

       acquiring.            .

 

Worked with a company to help them determine what was necessary for

       an adequate ground station for a very interesting deep space

       communications project.

 

Worked with a company that had a problem with the antenna radiation

       patterns from a packaged device. It had several antennas in it, all of

       which worked well on their own. But, electromagnetic simulation of

       the overall package, including internal structure such as circuit

       boards and batteries revealed the problems.

 

Designed, simulated, and developed a hybrid coupler that helped a

       company win an aerospace related contract.

 

Designed and developed QPSK and other I/Q modulators for various

       clients.

 

Measured the dielectric constant and loss characteristics of a material

       that had to have a new antenna design embedded in it.
