The CA-EP-2x2-738 from Microlab is a 2x2 Hybrid Directional Coupler that operates from 694 to 3800 MHz. This 3.1 dB coupler provides an isolation of more than 23 dB and has a VSWR of less than 1.25:1. It can handle an input power of 200 W (per input) and has a PIM of better than -155 dBc (tested with 2x43 dBm tones). This 50-ohm coupler is suitable for combining two wireless carriers in the band to a single antenna feed or distribution cable. In situations where two similar feeds are required, both outputs of the coupler can be used, eliminating the need for a term and a splitter. It is available in an IP65-rated housing that measures 155 x 47 x 36 mm with 4.3-10 or N-type connectors. This coupler is ideal for use in commercial wireless and private LTE needs in enterprise DAS applications.
