Kirkland, Washington - BBTLine (BroadBand Transmission Line) announces the introduction of model BBTLine_Coupler1_SMP, an SMP-connectorized (Smooth-Bore SMPs) RF bidirectional coupler.

RF Specifications:

  • BroadBand:  0.8 to >6 GHz Operation
  • Low Loss:  <0.8 dB at 6 GHz
  • Good Directivity:  >20 dB to 5.6 GHz
  • Return Loss:  19 dB min all ports
  • RoHS Compliant

Although there are endless RF power splitters / combiners to choose from on the market, once you start narrowing the search criteria down to 1) Broadband, 2) Surface Mount, and 3) Higher RF Power Rating characteristics, the number of choices is reduced considerably. BBTLine's line of surface-mount splitters / combiners addresses this market deficiency.


  • $100 for quantity 1 to 3
  • $90 (10%) for quantity 4 to 6
  • $80 (20%) for quantity 7 to 9
  • $70 (30%) for quantity 10+
