Surface Mount Diplex Filter
The CX6002 filter module allows two-way communication between the customer premise equipment (CPE) and the cable network with minimal crossover interference between the downstream broadcast frequency spectrum and the customer-to-Internet upstream communication band. In most bi-directional cable applications, the 54 to 864 MHz frequency range carries the downstream broadcasts and the 5 to 42 MHz range carries the upstream communications. The CX6002 diplex filter separates these upstream and downstream signals, delivering a low-pass signal (less than 42 MHz) at one port and a high-pass signal (greater than 54MHz) at the second port. The design provides excellent return loss, crossover isolation and port-to-port isolation.
Measuring 1.00 × 0.5 × 0.23 inches, the CX6002 surface mount module minimizes board space, enabling compliance to DOCSIS and other network requirements. This diplex filter needs no tuning, further reducing assembly costs for the customers.
