EHF-2BG2450

Balun Overview

The EHF-2BG2450 is a surface-mount balun manufactured by Panasonic Electronic Components, designed for operation within the 2.4 GHz to 2.5 GHz frequency range. It provides impedance transformation between unbalanced and balanced ports with values of 50 Ohms and 200 Ohms respectively. The device features a phase difference of 180° ±15°. Key electrical specifications include a maximum insertion loss of 1.0 dB and a minimum return loss performance. The component is housed in an 0805 (2012 Metric) package, suitable for automated surface mount assembly processes.
