ADTT1-1+ is a surface mount RF transformer with a 1:1 impedance ratio, designed for impedance matching and balun applications in the 0.3 to 300 MHz range. It has a 50 Ω characteristic impedance and handles up to 0.25 W RF power and 30 mA DC current. The device exhibits typical insertion loss of 0.3 dB referenced to mid-band, with return loss exceeding 18 dB within its 1 dB bandwidth. Amplitude unbalance is 0.15 dB typ. and phase unbalance is 1 deg. typ. within the same bandwidth. It operates from -20°C to 85°C and is aqueous washable. The case style is CD542 with dimensions 7.87 mm × 6.91 mm × 5.59 mm. It is RoHS compliant and protected under U.S. Patent 6,133,525.
