MACOM launches plug-in and surface-mount DOCSIS 3.1-compliant CATV diplex filters

M/A-COM Technology Solutions Inc of Lowell, MA, USA (which makes semiconductors, components and subassemblies for analog RF, microwave, millimeter-wave and photonic applications) has launched three families of diplex filters designed for DOCSIS 3.0 and DOCSIS 3.1 infrastructure equipment. Available in plug-and-play vertical and horizontal form factors along with surface-mount configurations, the new high-performance diplex filters are suited to use in CATV infrastructure spanning nodes, system amplifiers, line extenders, drop amplifiers and RF-over-glass (RFoG) optical networking unit (ONUs).

The new MAFL-0110XX series of diplex filter platforms cover the key industry frequency splits of 42/54, 65/85, 85/105 and 204/258MHz, and operate from 5MHz to 1218MHz. The compact plug-and-play filters provide what is claimed to be superior insertion loss, return loss, rejection and cross-over-isolation performance, and are designed and tested to meet exacting infrastructure quality and reliability requirements. Each filter platform is easily expanded to cover other frequency splits.

The diplex filter platforms are the newest additions to MACOM's portfolio of RF components specifically designed to comply with the DOCSIS 3.1 standard for high-bandwidth data transfer over hybrid fiber-coaxial (HFC) infrastructure. MACOM says that its domain expertise, coupled with a global sales and applications support network, ensure that designers are afforded the products and support required for accelerated market deployments for DOCSIS 3.1-compliant equipment.

"MACOM's high-performance pluggable and SMD filter platforms provide network equipment designers with full turnkey solutions that facilitate accelerated amplifier developments," says Graham Board, senior director of Carrier Networks at MACOM. "With so much focus on amplifier performance for DOCSIS 3.1 infrastructure it is easy to lose sight of the importance of the filter and passive components in the cascade. MACOM's filters are designed to deliver superior RF performance, thus enabling optimal GaAs or GaN amplifier cascades for network equipment."
