Teleste CX3 L065, 1.2GHz Amplifier [TEL-CX3L065]
Teleste CX3 is a compact dual output amplifier with forward gain up to 43 dB. Based on the latest GaN amplifier technology, the CX3 offers high output level (Umax 110.0 dBμV, 138 channels) and wide gain range, both helpful when networks take the next step and become DOCSIS 3.1 compliant.
Key features
- 1218 MHz downstream
- 204 MHz upstream
- Electrical adjustments with local user interface
- GaN performance
- Cable simulator selection at input
- High gain/low gain selection
- Flat/sloped output selection
- Excellent ESD and surge protection
Simple and reliable
Designed quality and robustness in mind, the CX3 not only provides reliable performance, but also ensures great usability through a local user interface. All this comes in a compact format, making the CX3 a great all-around amplifier for modern bidirectional networks, in which cost efficiency and easy installation are prime concerns.
Smooth migration
The new CX3 amplifier offers operators a smooth migration path to DOCSIS 3.1-compliant technologies. It can be used in 860 MHz / 1 GHz / 1.2 GHz networks while the return path supports frequencies up to 65 MHz, 85 MHz and 204 MHz.
Local user interface
The CX3 has a local user interface consisting of a four digit 7-segment display and three push buttons.
