Thu, 04/03/2008 - 10:53am
Mini-Circuits announces its surface-mount RF transformer model TCN2-45+ that maintains typical insertion loss of 1.5 dB from 3.3 to 4.5 GHz. Based on reliable low-temperature-cofired-ceramic (LTCC) for small size, the 50Ω transformer has a secondary/primary impedance ratio of 2, and it is suitable for use in WiMAX designs. The transformer achieves typical amplitude unbalance of 1 dB and typical phase unbalance of 5° (relative to 180°). It measures 0.126 inchesࡦ.063 inchesࡦ.035 inches (3.20ࡧ.60ࡦ.89 mm), and it can handle input power levels to 5 W.
