Document 282-1 Diplex Filters For DOCSIS 1.0, 1.1, 2.0 These diplex filter modules provide both low pass and high pass filtering in low cost units that meet the requirements of the DOCSIS 1.0, 1.1 and 2.0 standards.They are intended for two-way broadcast applications like cable modems, settop boxes and HFC cable network equipment. The DPX-C parts are low-profile surface mount units that require a minimum of board space. The DPX‑B are shielded and come with an integrated coaxial F connector. In addition to the designs shown here, Coilcraft can custom-engineer diplexers for specific applications.
