300W RF Directional Coupler(698-4000MHz,-160dBc, 4.3-10 Female, IP65)
RF directional couplers are passive devices that couple power travelling through the device to another port enabling the signal to be used in another circuit. RF directional couplers can be implemented using a variety of techniques including stripline, coaxial feeder and lumped or discrete elements. Directivity is a measure of how well the coupler isolates two opposite-travelling (forward and reverse) signals. In the case of measuring reflection coefficient (return loss) of a device under test, directivity is a crucial parameter in the uncertainty of the result.
Topwave Telecom model TPW-DC-XX-740-160-41F(XX means coupling in dB), is 698-4000MHz 4.3-10 female low PIM directional coupler. The directional coupler wide frequency range covering UHF, Tetra, 2G/3G/LTE, even used for 5G. Meanwhile, the PIM can reach -160dBc to avoid any mutual interference between signal channels. Topwave directional coupler perform very well on applications due to the high directivity and low loss.
