mmW anechoic chamber For Combined mm wave OTA Test
BJ-8853 Compact Anechoic Chamber with 4-Axis Positioner
● For 5G mm Wave far field OTA test
● Suitable for DUT size < 7"
● For Mass Production test application.

● 5G mm wave OTA measurement in a compact footprint with max far field distance up to 250mm to fit various DUTs for cost effective mass production solution
● Operation frequency from 700MHz to 50GHz
● 700MHz to 50GHz RF Isolation > 70dB

● Absorber reflective:<-30dB in FR2 frequency bands
● It contains a 3-axis linear movement plus 1-axis rotation positioner, in order to move any DUT antennas to the test area against the same ref antenna on top of the chamber
● It can support any DUTs with <7”size
● Input AC power: 100-240V AC 50Hz;
