AC2500 Amplifier
The AC2500 is a dual active output amplifier with 2 x 43 dB operational gain. It offers high output level (111.5 dBμV, 112 channels) and supports 1.2 GHz/204 MHz bandwidth.
The AC2500 amplifier is equipped with the latest technology and delivers incredible performance, flexibility and cost-effectiveness. This amplifier can be used as high gain distribution amplifier, but also as a lower gain trunk amplifier with bridger output. The AC2500 also complies with the DOCSIS 3.1 standard, an important feature designed to meet future service requirements.
Features at a glance:
- 1.2 GHz bandwidth
- Forward amplifiers use GaN HEMT and GaAs pHEMT technology
- GaAs push-pull return amplifier on the motherboard
- Temperature compensated forward and return path
- Flexible 862/1006/1218 MHz interstage slope pivot point selection
- Excellent ESD and surge protection
- Remote power supply with PFC
- Fixed station memory for electrical identification
- Optional AC6188 temperature compensating MLSC unit with RIS
- Optional AC6158 agile pilot ALSC unit with RIS
