Device Overview

General Description

The PBR-0012 is a 300 kHz to 12 GHz high isolation power combiner. This power combiner features a unique hand tuned construction based on a bridge coupler that enables 35 dB typical isolation across the operational bandwidth. High isolation power combiners are ideal for power combining uncorrelated signals, such as when performing intermodulation distortion (IMD) tests like IP2 and IP3. Their higher insertion loss and uncontrolled phase balance makes them unsuitable for power dividing applications.
