Mini-Circuits 1:1 CORE & WIRE Transformer, 1 - 400 MHz, 75Ω ADT1-1WT-1+

The ADT1-1WT-1+ is a surface-mount RF transformer designed for 75Ω impedance applications from 1 to 400 MHz, featuring a 1:1 impedance ratio and a maximum insertion loss of 1 dB across the band. It offers a typical return loss of 21 dB from 1 to 250 MHz, with amplitude and phase unbalance not exceeding 0.7 dB and 5 degrees, respectively. The component is housed in a CD542 case measuring 7.87 mm in length, 6.91 mm in width, and 2.84 mm in height, with a weight of 0.20 grams. It operates from -20°C to +85°C, supports up to 250 mW RF power, and handles 30 mA DC current. The transformer is aqueous washable and features a leaded surface-mount configuration.
