Modern mobile devices usually do not have an external

antenna connector. Connection to a radiocommunications

tester must therefore be made over the air. The link be-

tween the device under test (DUT) and the test equipment

should be reliable and path losses kept to a minimum.

Interference from external radio sources should be pre-

vented as far as possible. The R&S®CMW-Z10 RF shield

box with the high-quality R&S®CMW-Z11 antenna coupler

together perfectly meet these requirements.

The R&S®CMW-Z10 is made of solid aluminum. It is firmly

closed by means of a lever handle with a defined stop. The

bottom and cover will not distort under normal conditions.

This ensures uniform compression of the sealing cords

provided around the entire box – an important prerequisite

for effective RF shielding. The cover is lined with absorber

material, which minimizes reflections.

The antenna structure on the R&S®CMW-Z11 antenna

coupler board has been optimized to enable an excellent

radio connection between the DUT and the tester. The

highly broadband spiral antenna allows a wide variety of

applications. Further highlights of the R&S®CMW-Z11 in-

clude low coupling attenuation and the ability to place the

DUT at any desired position inside the box without affect-

ing attenuation caused by reflection.

The R&S®CMW-Z10 RF shield box with the

R&S®CMW-Z11 antenna coupler clearly set

standards. Offering excellent shielding effectiveness

and superior coupling characteristics, both devices

can be used for frequencies up to 6GHz. These

outstanding features combined with a modular

options concept make the R&S®CMW-Z10

with R&S®CMW-Z11 indispensable for any

radiocommunications tester.
