TDK HHM1727D1 is a multilayer chip balun designed for WiMAX applications. It has an unbalanced impedance of 50 ohms and a balanced impedance of 50 ohms. The frequency range is 3300 to 3900 MHz. The unbalanced port return loss is 10 dB min, the phase imbalance at the balanced port is 180±15 deg, and the amplitude imbalance at the balanced port is 0±1.5 dB. The insertion loss is 1.2 dB. The attenuation is 11 dB min [1700 to 1900 MHz] and 4 dB min [1900 to 1980 MHz]. The power capacity is 0.5 W max. The operating temperature range is –40 to +85 °C. The storage temperature range is –40 to +85 °C.
