HBR Directional Coupler, 4.8 dB, 700 to 3800 MHz

PCM-DC48-6938.432

Locally Stocked

Directional Couplers are used to develop complex RF transmission systems where unbalanced signal power levels are required, or to counteract and balance an unbalanced system.

This 4.8 dB (often shortened to 5 dB) directional coupler has been designed for use in 5G transmission and in-building coverage systems, supporting a wide frequency range from 700 to 3800 MHz, extremely low intermodulation with a -160 dBc PIM rating, and using 5G-compatible 4.3-10 connectors. The model provides exceptional inter-port isolation between coupled and output ports.

With an IP65 ingress protection rating the power divider can be used indoors or outdoors. A sturdy removable stainless steel mounting bracket is included.
