30dB Directional Coupler 694-2 700MHz 50W N-type Indoor

Please Register or call for more information

Microlab CK-50N series of N type Directional Couplers, is a multi section, quarter wave, microstrip design for indoor applications covering all wireless bands from 694 to 2,700 MHz. Units couple off a defined fraction of signal from 5 to 20 dB with minimal reflections or loss.

The wide frequency range allows use with multiband antennas and leaky cable systems and in wireless base stations. With minimal solder joints and an air dielectric, the dissipative loss has been minimized and reliability enhanced.

These Directional Couplers may also be used as Unequal Dividers or Tappers, which are usually specified by the power ratio between outputs. For convenience these are shown in the table.

  • 5 to 30 dB Coupling Values
  • Good Directivity VSWR & Loss
  • Wideband Cellular to WiMAX
  • 50 Watt Average Power
  • RoHS Compliant
  • Effective as Tappers for DAS In-Building Systems
