CX3R-D Amplifier
The CX3R-D is a compact amplifier with a 1.2 GHz frequency range in the downstream and up to 204 MHz in the upstream. The high-performance output stage uses the latest technology to improve RF performance over the entire frequency range and ensures low power consumption. Adjustments use electronic controls, eliminating the need for plug-in attenuators or equalizers. It is small in size and light in weight but delivers performance and functionality on a scale that makes it ideal for any distribution challenges at a competitive price.
