RF Techniques is a leading designer and manufacturer specializing in high temperature brazed High Power Resistors, High Power Attenuators and High Power Terminations for the high reliable Microwaves and RF applications. RFT's high reliability brazed products are consistently utilized in the most demanding environments in many military and commercial programs, successfully meeting the most stringent performance standards every time.



RF Techniques utilizes a high temperature brazing process that yields the lowest possible thermal resistance at higher temperature device operation. This proprietary processing also ensures higher reliability and longer performance life. The high temperature fluxless brazing process eliminates the concerns of lead separation during soldering operations and provides a joint without corrosive flux residue. These resistor products will withstand substantial forces applied to the lead due to different rates of contraction and expansion of the lead during temperature variations.

Advantages Of Brazed Products

  • Higher Operating Temperature, Higher Reliability, Better Tolerance, Lower Rejects
  • Brazing is done over 800 degree C
  • Power deration is up to 250 degree C.
  • Leads are capable of up to 5 lbs. of pull test and bend test.
  • Brazing provides higher power handling & lowest thermal resistance.
  • Higher temperature processing also ensures greater reliability and overall performance during thermal cycling.
  • Brazed devices are capable of withstanding much higher temperature for short period of time without damage.
  • This high temperature capability provides the user with improved system reliability and a wider margin of performance under abnormal operating conditions.
  • Brazed device will withstand substantial forces applied to the lead due to different rates of contraction and expansion of the lead during temperature variations.
  • With brazed construction, the customer need not have to worry about leads coming off during soldering operations.
