House connection amplifier – 47/85-1006 MHz – F-Con. – Gain 40/34/30 dB – Level St./Dec.: 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 leveling via rotary switch, large setting range (20 dB), small step size (1 dB)
- Basic configuration via jumpers
- Exactly 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 input (switchable)
- With directional coupler at output
- Internal LED function indicator
- Overvoltage arrester at input and output
- Comply: EN 60728-11, EN 50083-2 and EN 60065
- Cast housing with F connections (VOS 137/RA, VOS 138/RA) or PG 11 connections (VOS 139/RA: order cable fittings separately, not included)
- For use in locations protected from the weather
- The amplifier complies with the requirements of the EMC Directive 2004/103/EC and the Low Voltage Directive 2006/95/EC valid at the time of delivery
