Product Description
In a microwave system, one channel of microwave power is often divided into several channels in proportion, which is a problem of power distribution. The components that realize this function are called power distribution components or couplers, which mainly include: directional couplers, power distributors, and various microwave branch devices. The coupler is a radio frequency device that extracts a small part of the signal from the wireless signal trunk channel. It is a power distribution device like the power divider. The difference is that the coupler is an unequal power distribution device. The use of the coupler and the power divider is mainly to achieve a goal-to make the transmission power of the signal source evenly distributed to the antenna ports of the indoor distribution system as much as possible, so that the transmission power of each antenna port is basically the same. Waveguide high directivity directional coupler
Covering the full waveguide bandwidth, the coupling degree can be selected from 3-60dB, the flatness is optimal, and the cost is higher than the cross coupler.
Waveguide Cross Directional Coupler
Covering 20% of the waveguide bandwidth, the selectable range of coupling is 20-60dB, and the directivity of 23-15dB is better than that of a waveguide ring coupler.
Waveguide ring coupler
Covers 20% of the waveguide bandwidth, with a selectable range of 20-60dB, directivity of 20-15dB, and small size. Mostly used for system detection below 10G.
3dB directional coupler
Covers 20% of the waveguide bandwidth, 3dB coupling, and the two outputs are 90 degrees out of phase
Probe coupler
Covering 20% of the waveguide bandwidth, the selectable range of coupling is 10-60dB, non-directional, large standing wave and smallest volume.
