These TUO transformers are intended for output impedance matching applications in the 2-300 MHz frequency range up to 1KW. The winding material is semi-rigid coax cable. The primary and secondary windings are DC isolated. Depending on the power levels involved, the band may have to be divided into two or three segments. The Type "U" transformers require a presence of magnetic material, such as ferrite to increase the winding inductance, for operation below approximately 75MHz. The magnetic material is available separately.
The TUO transformers are available in the following windings:
2 Turn 1:4 Impedance ratio
3 Turn 1:9 Impedance ratio
4 Turn 1:16 Impedance ratio
The TUO transformer is available manufactured with standard solder or with lead free solder.
