Broadwall Directional Coupler

WFTelegom manufactures a standard product line of multi-holebroadwall directional couplers covering a wide frequency range. Theoptimum electrical characteristics of high directivity and couplingfatness are achieved utilizing a precision machined Tchebyschefcoupling hole distribution and a precision ground tapered loadelement in the secondary arm. Directional couplers are typicallyused for power sampling,frequency monitoring, especially in thetest setups where power refection measurements are requiredAdditional sizes and special configurations are available on request

Product Description

1.Radar Cross Section

We provide state-of-the-art radar cross section measurement systems suitable for measuring small-scale test articles and/or full-scale vehicles depending on customer requirements.
2.Radome Testing
The military and commercial aircraft carry a vast array of antennas for specialized and vital functions. Communications, navigation, weather and fire control antennas must perform as specified to meet safety and mission requirements. Radomes must conceal and protect antennas without interfering with or degrading transmit/receive capabilities.
3.Satellite Antenna Testing
RF testing of flight hardware poses challenges that are unique to the space industry and antennas specifically, are often delicate and gravitationally sensitive. Minimizing or even avoiding motion of these antennas during testing is highly desirable for two reasons: Firstly, it minimizes risk to the antennas. Secondly, the standard gain horn antenna can be deployed with respect to a fixed gravity vector.
4.Wireles
Wireless networks rely on antennas and our products allow for the reliable characterization of these antennas. We offer test systems that are suitable for evaluation of electrically small handset or other UE antennas, as well as electrically large base station antennas.
