PRO-PHY 380-2700-3 dB
200 W 3 dB Coupler (90° Hybrid)
Description
- Hybrid Coupler with 3 dB coupling covering the 380 – 2700 MHz band.
- Excellent high-power performance.
- If working as combiner max. input power 100 W per port into max. two ports of the four ports.
- If working as splitter 200 W into max. one port.
- 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.

Additional Information
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.
