Bird - The RF Experts
350-BD Series

3-Way, 350 Watt UHF RF Combiner/Dividers

Bird's 350-BD Series, Power Dividers Signal Combiners are world renowned for their high-quality, robust construction and conservative power ratings. The use of non-magnetic materials and plating provide naturally lower intermodulation performance and safety when used in high magnetic fields such as MRI.

Note: To achieve Maximum power dissipation under mismatch conditions it is necessary to provide a heat sink that maintains a case temperature at or below 100 °C
