TDLLC is equipped with in-house facilities for electronic and electromechanical development, including separate Analog and Radio Frequency laboratories. Machine shop essentials are also included for electromechanical prototyping.  
 
 
  Technical Development was responsible for equipment procurement (including screen room) and setup of a low cost in-house EMI pretest facility for a growing defense contractor, and continues to operate the facility. Screen room interior shown.  
 
 
  TDLLC performs in-house design and prototyping of all power and signal magnetics.  
Please contact us with any questions about product feasibility, our experience, and any other inquiries you may have.
 
 

A word about EMI design and in-house facilities: 

• 

TDLLC has experience in FCC part 15, EMI CE requirements, MIL-STD-461, and DO-160 sections 22 and 25.

TDLLC maintains in-house facilities for affordable pretest for most of the foregoing.
TDLLC works to MIL standards, including ‘704 and ‘464, and PCB aspects of MIL-STD-810. Experience covers design through qualification.
 
An intriguing Consideration:
 
A capacitor is charged to 10V, and is connected to another of the same value with a switch. When the switch is closed, the voltage on both capacitors becomes 5V, which meets the law of conservation of charge, Q=CV. But when the before and after energies are calculated according to E=1/2 CV² , half of the energy appears to disappear. This is true because the capacitance doubles, but the voltage halves. Hmmm. How?
 
 
TDLLC possesses all test equipment needed for analog, RF, and EMI design, including the network analysis S parameter transistor test fixture shown.
