The Smart Bias Tee provides low RF signal insertion loss from port 1 to port 2 and vice versa. The measures taken to protect against static discharge and lightning ensure a high level of reliability and operational safety. • 782 10253: 12 V version for use near the BTS, in order to feed-in DC voltage and RCU control signals into a feeder cable • 782 10254: 12 V version for use near the antenna, in order to control an RCU (only required if no TMA is in use) • 782 10255: 24 V version for use near the BTS, in order to feed-in DC voltage and RCU control signals into a feeder cable • 782 10256: 24 V version for use near the antenna, in order to control an RCU (only required if no TMA is in use) 782 10253 782 10254 782 10255 782 10256 Smart Bias Tee 10802-H 936.2484/g Specifications: 782 10253 782 10254 782 10255 782 10256 12V/BTS 12V/Antenna 24V/BTS 24V/Antenna Connectors Port 1 7/16 DIN male Port 2 7/16 DIN female Port DC/RCU 8-pin male 8-pin female 8-pin male 8-pin female (IEC 60130-9) (IEC 60130-9) (IEC 60130-9) (IEC 60130-9) Pin 1: 12 VDC in Pin 1: 12 VDC out Pin 6: 24 VDC in Pin 6: 24 VDC out (Pin 3: RS485-B, pin 5: RS485-A. pin 7: DC return (grounded), other pins: not connected) Maximum input power Port 1 or Port 2 ≤ 750 watts (800–2170 MHz) Port DC/RCU <2.5 A / +8 – +14 VDC <2.5 A / +8 – +14 VDC <2.5 A / +14 – +30 VDC <2.5 A / +14 – +30 VDC General Specifications: Frequency range 800–2170 MHz Impedance 50 ohms VSWR < 1.1:1 (800–2170 MHz) Insertion loss Port 1↔Port 2 < 0.1 dB (800–2170 MHz) Isolation for DC and RCU signals Port 1↔Port 2 >70 dB Port 1↔Port DC/RCU >70 dB Port 2↔Port DC/RCU 0 dB Intermodulation (2x20w) IM3: <-160 dBc Power consumption Typically 0.6 watt Lightning protection 3 kA, 10/350 ms pulse Operating temperature -40° to +60° C Modem carrier frequency 2.176 MHz IP rating IP 66 (indoors or outdoors) Dimensions 4.3 x 3 x 1.7 inches (108.7 x 76 x 42.8 mm) Weight 2.9 lb (1.3 kg) Shipping dimensions 6.6 x 4 x 3.4 inches (167 x 102 x 86 mm) See reverse for order information.

Please note:The Smart Bias Tees are designed to operate under the environmental conditions as described in ETS 300 019-1-4 class 4.1 E and have passed environmental tests as recommended in ETS 300 019-2-4.

The installation team must be properly qualified and also be familiar with the relevant national safety regulations.

The limits for the coupling torque of RF connectors, recommended by the connector manufacturers must be obeyed.

Tightening torque for fixing the AISG connector must lie between 0.370.74 lb/ft (0.5 1 Nm).
