CX3 Amplifier
The CX3 is a compact dual output amplifier. Based on the latest GaN amplifier technology, the CX3 offers a high output level (Umax 110 dBμV, 138 channels) and wide gain range, both helpful when networks take the next step and become DOCSIS 3.1 compliant.
Designed with quality and robustness in mind, the CX3 amplifier is not only providing reliable performance but also ensures great usability. All this comes in a compact format, making it a great all-around amplifier for modern bidirectional networks where cost efficiency and easy installation are prime concerns.
