These current devices are based on the W1JR Baluns. They are used connect 75 ohm coaxial cables, like CATV's to 50 ohm systems. It can be used the other way: Insert a 50 ohm device or coaxial cable into a 75 ohm system.
50 to 75 unbalanced to unbalanced transmission line transformer
- Use of low loss 75 ohm CATV cable in 50 ohm systems
- Two can be used at the ends of a CATV low loss coaxial to step down to 50 ohm impedance or two can be used to insert a 50 ohm coaxial cable or device in a 75 ohm transmission line system.
- 50 Ω unbalanced to 75 Ω unbalanced transformation.
- Rated for 5 kW CW and 10 kW SSB, these impedance transformers offer the same quality as our well known W1JR baluns.
- N-type connectors on either side of the box, also available with SO-239 and 7/16DIN connectors or combinations of them.
- 4-3/4" x 3-3/4" x 2-1/4" inches (120 mm x 95 mm x 58 mm) cast aluminum boxes.
AS-50:75 unun transformer SWR, Impedance Magnitude (Zmag) and Return Loss (S11) plot
This is the Insertion Loss (S21) of two unun transformers connected back to back at the 75 ohm side. To get the Insertion Loss (S21) of one transformer, divide the dB quantities by 2. Example: At 80 MHz the S21 of one balun is 0.315 dB.
AS-50:75-1N - UNUN transformer 50 to 75 ohm (1 to 1.5 ratio), 50 ohm coaxial cable to CATV Transformer. 5 kW CW / 10 kW SSB. N-type connectors. 1.8 to 60 MHz.
