CX3-D – CX3-DG Amplifiers
The CX3‑D/CX3‑DG are compact dual‑output amplifiers with a 1.2 GHz downstream frequency range and up to 204 MHz in the upstream. The amplifier stage is based on high‑performance GaN, ensuring low power consumption. All adjustments use electronic controls, eliminating the need for plug‑in attenuators or equalizers.
Features at a glance:
- GaN amplifier technology
- Diplexers for 65/85/204 MHz upstream
- Bypass port at the input
- Remote powered
- Optional: remote ingress switching
- Optional: power save
