ADT1 is a passive balun coupler (RF transformer) module based on the ADT1-1WT chip, primarily used for bidirectional conversion between single-ended and differential signals in RF circuits. It features a passive design with compact structure, high reliability and wideband operation, effectively performing impedance matching and balanced-unbalanced transformation, making it an ideal basic component for RF front-end design. Widely used in balanced amplifier design in RF communication systems, antenna and receiver front-end impedance matching, mixer and high-speed ADC/DAC differential signal conversion, as well as various radio transceiver equipment, test instruments and RF R&D experimental scenarios requiring single-ended to differential signal conversion and wideband impedance matching (note: not suitable for DC or ultra-low frequency applications).
Module function: single-ended to differential / differential to single-ended (passive balun) Operating frequency: 50 KHz – 800 MHz Insertion loss: typical 4 dB (<4.0 dB @<0.5GHz) Max input power: 27 dBm (0.5W) Impedance & VSWR: 50 Ω, VSWR 1.5:1 Connector type: SMA female
