Hybrid Coupler


Hybrid combiner for public safety bands with 35-40 dB isolation between ports. This unique combiner allows for unequal power combining in the low frequency UHF band. It provides a 2 dB insertion loss through one path and 4 dB in the second path. This allows higher power transmitters to combine equally with a lower power transmitter. Optional external loads are available in a wide range of power levels, if needed, for 1x2 or 2x1 applications. Normally supplied with Type N connectors, and with other standard connector options. The Model HD-B16 is also suitable for applications that require excellent low PIM.
