TC-93060A/61A, Flat Type Antenna Coupler, performs RF Coupling for Near Field Electromagnetic Field of DUT as installed in the  RF Shield Box. It is stable and has steady RF Coupling characteristics within range of 800 ~ 6000 MHz that can be applied to test various types of devices using 5GHz frequency range such as Wifi and LTE. It provides the most stable test environment. TC-93060A or TC-93061A would be selected depend on DUT’s antenna characteristics as of TC-93060A and TC-93061A for each has different Polarization characteristics of LHCP and RHCP.
