DH1660 Amplifier
The DH1660 is a compact 1 GHz two-way amplifier with an integrated power supply designed for applications and requirements in customer premise in-house (NE4) network installations to compensate for long drops and excessive splitting losses.
The DH1660 is a single active output amplifier with 31 dB maximum gain in the forward bandwidth and 25 dB in the reverse bandwidth. The DH1660 features variable 0…18 dB attenuators for down- and upstream and a variable 0…18 dB input equaliser for downstream.
Features at a glance:
- Frequency range up to 1 GHz
- Forward path gain max. 31 dB
- Return path gain max. 25 dB
- Integrated switched-mode power supply
- Compact and robust housing
- Adjustable gain and slope controls for forward path
- Gain control for return path
