HHM1715E1

Balun Overview

The TDK HHM1715E1 is a signal conditioning LTCC balun transformer designed for RF applications. It operates within a frequency range of 3300 MHz to 3900 MHz, providing a bandwidth of 600 MHz centered at 3.6 GHz. The component performs impedance transformation between 50 Ohms unbalanced and 100 Ohms balanced ports. It features an insertion loss of 1 dB and utilizes SMD/SMT termination. The device is housed in a 0603 (1608 metric) package with dimensions of 1.60mm length, 0.80mm width, and 0.60mm thickness. It supports board mount installation and functions within a temperature range of -40°C to +85°C.
