Morita Tech has developed the extra wide band antenna coupler WA-667S that can cover frequencies from 600MHz to 67GHz.
WA-667S covers frequencies up to 600MHz-67GHz and can be used for spurious testing by OTA of modules and devices such as 5G and next-generation Wi-Fi. The wideband wave coupler is a high-frequency device whose main purpose is “reception” at a short distance of “close contact to about 10 cm” with the object to be measured. The connector is 1.85 mm.
