CATV HFC Infrastructure

In HFC (Hybrid Fiber-Coaxial) networks, MACOM offers a family of DOCSIS3.1 Push-Pull and Power Doubler both GaAs and GaN solutions in both plastic and hybrid formats. The higher power levels combined with extended frequency requirements of D3.1 also place much greater demands on the passive components in the system amplifier. Passives need to negate system distortion. Macom also offers the broadest portfolio of D3.1 ready transformers, power dividers/combiners and couplers to meet these new system challenges. Diplex filters are also available delivering the lowest possible loss while maintaining very high isolation and return loss.  D3.1 extends frequency bands in both the forward and reverse paths. In order to meet the challenges of next generation architecture, Macom has also developed a family of 300MHz reverse path single-ended, differential and variable gain amplifiers.
