PRO-PHY 117-137-3 dB-...

200 W 3 dB Coupler (90° Hybrid)

  • Hybrid Coupler with 3 dB coupling covering the 117 - 137 MHz band.
  • Excellent high-power performance - 200 W.
  • Very low insertion loss over the entire frequency range.
  • Available with N(f), 4.3/10(f) or 7/16-DIN(f) connectors.

DESCRIPTION

  • 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.

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.

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.
