The HHM1522E1 with Signal Conditioning MULTILAYER BALUN is a BALUN for surface-mount devices (SMD) manufactured by TDK. It is designed to operate in the 900MHz band, combining the functions of a Balun and a Signal Conditioner. Its very low profile of 0.9mm is ideal for space constrained applications such as handsets, base stations, and terminals. The Ceramic Balun ensures a very low common mode noise level, while the Signal Conditioning circuit ensures very low losses. It also has a high efficiency, wide frequency range, and integrated EMI filter. The device is RoHS compliant and provides a low profile and lightweight solution.
