Mini-Circuits’ model SERT4-62HP-50W+ is a high-power, surface-mount-technology (SMT) RF transformer that converts a secondary impedance of 12.5 Ω to a primary impedance of 50 Ω (1:4 ratio) from 20 to 600 MHz. It exhibits extremely low insertion loss across the frequency range, at typically 0.4 dB, with return loss of typically 24 dB at 50 Ω. Well suited for commercial and military mobile communications systems, the compact SMT transformer measures just 0.93 × 1.22 × 0.47 in. (23.62 × 30.99 × 11.94 mm) but can handle as much as 50 W RF input power across the full frequency range. The RoHS-compliant transformer is designed for operating temperatures from -40 to +65°C.
