House connection amplifier | 47/85-1006 MHz | F-connector | gain 40/34/30 dB | level control/equalizer: 20 dB | 113/116 dBμV (60dB CTB/CSO, Cenelec 42 Ch.)
- House connection amplifier for modern HFC networks
- Remote powered via RF input (self-powered)
- Latest GaAs MMIC technology
- Very high output level with favorable energy balance
- High efficiency switching power supply
- New innovative operating concept:
– Simplified level adjustment via rotary switch, large adjustment range (20 dB), small step size (1 dB)
– Basic configuration via jumpers
– Precisely reproducible device settings
- Slot for additional functions in the forward path (e.g. deemphasis, system equalizer)
- Gain by interstage attenuation switchable with jumper 40/34/30 dB (delivery condition: 34 dB)
- Diplexer can be bridged (Band I operation possible without return path)
- Return path (active/passive/disconnectable) with various setting options permanently integrated
- Classification according to KDG 1 TS 140: Type D(4.4)
- Test sockets (F-connectors):
– Bidirectional at the input (can be switched on)
– With directional coupler at the output
- Internal LED function indicator
- Overvoltage arrester at input and output
- Complies: EN 60728-11, EN 50083-2 and EN 62368-1
- Cast housing with F connections
- For use in locations protected from the weather
- The amplifier complies with the requirements of the EMC Directive 2014/30/EU and the Low Voltage Directive 2014/35/EU valid at the time of delivery
