Smart Bias Tee<br />
800 – 2170 <strong>MHz</strong><br />
The Smart Bias Tee combines the performance of a<br />
standard Bias Tee (e.g. type 793 304) with the function<br />
of an additional modem (AISG standard) in order to<br />
provide either DC voltage as well as remote control signals<br />
via an RF feeder cable to a TMA or RCU.<br />
The Smart Bias Tee provides low RF signal insertion<br />
loss from port 1 to port 2 and vice versa.The measures<br />
taken to protect against static discharge and lightning<br />
ensure a high level of reliability and operational safety.<br />
• 782 10253, 782 10453: 12 V version for use near the<br />
BTS, in order to feed-in DC voltage and RCU control<br />
signals into a feeder cable<br />
• 782 10254, 782 10454: 12 V version for use near the<br />
antenna, in order to control an RCU (only required if<br />
no TMA is in use)<br />
• 782 10255, 782 10455: 24 V version for use near the<br />
BTS, in order to feed-in DC voltage and RCU control<br />
signals into a feeder cable<br />
• 782 10256, 78210456: 24 V version for use near the<br />
antenna, in order to control an RCU (only required if<br />
no TMA is in use)<br />
