 Typical application (above) of U-type Transformers in a 5 to 175 MHz, 300 W amplifier.

 

     The Type "U" Transformers are intended for input, output and interstage impedance matching apllications in push-pull amplifiers in the 2 to 300 MHz frequency range. Depending on the power levels involved, the band may have to be divided into two or three segments. The Type "U" transformer requires a presence of magnetic material, such as ferrite, to increase the winding inductance for operation below approximately 75 MHz.

 

Key Features:

  • Power handling capability exceeding 1kW
  • Primary and secondary D.C. isolated
  • Impedance ratios from 1:1 to 16:1 available
  • Small physical size

 

 

    

     The type "U" transformer is not a stock item due to a large variety of requirements in mechanical aspects, power level, impedance ratio and bandwidth. Contact us about your specific requirements and our low prices.
