  • Hybrid Coupler with 3 dB coupling covering the 380 – 520 MHz band.
  • Excellent high-power performance.
  • If working as combiner max. input power 50 W per port into max. two ports of the four ports.
  • If working as splitter 100 W into max. one port.
  • Very low insertion loss over the entire frequency range.
  • Available with N(f), 4.3/10(f) or 7/16-DIN(f) connectors.
  • 3 dB 90° Hybrid Couplers also known as quadrature hybrids are a passive four port device that can be used in many different modes depending on the application. It can be used as a splitter, combiner or injection of a signal into a signal path.

Different modes of the 3 dB Hybrid Coupler

Coupler splitter mode:
Divides the signal into two equal components with a 90˚; phase difference that can be used to split signals from tower top amplifiers to the base station receivers.

2000x1078-0-0-280x151-pro-phy-diagrammer-2-NY GB

Coupler combiner mode 1:
If the same signals is applied at the input ports with a 90˚; phase difference the signals adds up on one port.

2000x1078-0-0-280x151-pro-phy-diagrammer-3-NY GB

Coupler combiner mode 2:
Combining two non-coherent signals that are available at both ports.

Common applications of 3 dB 90° Hybrid Couplers
  • Combining two transmitters with very narrow spacing to one common antenna or to a DAS network.
  • Combining two carrier inputs to one or two antennas or leaky feeder/radiating cables.
  • Splitting signals from tower mounted amplifiers to base station receivers.
