HHM1570B1

Balun Overview

The HHM1570B1 is a balun transformer manufactured by TDK Corporation, designed for RF applications. It operates within a frequency range of 4.9 GHz to 5.95 GHz and provides an impedance transformation ratio of 50 Ohm to 100 Ohm. The component utilizes Low-Temperature Co-Fired Ceramic (LTCC) technology to achieve low insertion loss and latency performance. It is housed in a compact 0805 metric (2012) surface-mount package with dimensions of 2.00mm length, 1.25mm width, and 0.95mm thickness. The device supports an operating temperature range from -40°C to 85°C.
