BALUNs
Only CWS ByteMark manufactures these Baluns and Ununs based on Dr. Jerry Sevick's (W2FMI) design. The construction and design of these Baluns and Ununs are a result of joining forces between Jerry Sevick (W2FMI)and James Lau, the chief engineer and a principal at CWS ByteMark. If you need some custom features, please call us.

Standard Features:

  • Custom permeability core is used to obtain the widest bandwidth
  • 1 Mhz to 50 MHz with lowest energy loss. Typically insertion loss is less than 0.2 dB
  • High Power Handling Capability - up to 10 Kw
  • Highest voltage breakdown ratings
  • Both "Current" and "Voltage" types available
  • Aluminum case with SO239 connector and 2 ceramic feed through post as outputs. Custom case, fully encapsulation and other customization are available at added cost.
  • Dimensions: 2 Sizes :- Dimension A and Dimension B are as given below
  • Mounting holes.
  • All items are available in stock for immediate delivery.

Dimensions:
Dimension A : Height = 5.5" ( 6.8" including the flange). Width = 3.8". Thick or depth = 2.3".

Dimension B : Height = 5.8" ( 7.3" including the flange). Width = 4.8". Thick or depth = 3.6".
