Device Overview

General Description

The PBR-0012SMG is a 10 MHz to 12 GHz surface mount high isolation power combiner. This power combiner features a unique hand tuned construction that enables 30 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.
