Please note:<br />

In order to achieve spurious emission requirements acc. to the AISG and 3GPP specifi cations, the CCU must<br />

be operated with a suitable Bias-Tee (Kathrein 78210429). The Bias-Tee must provide a minimum attenuation<br />

of 55 dB from 400<strong>MHz</strong> to 2170<strong>MHz</strong> and 30 dB from 2,17 GHz to 12,75 GHz between the DC-port and both<br />

RF-ports.<br />
