Surface Mount RF Transformer, 50Ω, 5 Watt, 10 to 450 MHz

Mini-Circuits’ SYTX2-451-5W+ is a high-power, DC isolated surface-mount transformer with a secondary/primary impedance ratio of 2 for applications from 10 to 450 MHz. With proper heat sinking, the transformer is capable of handling RF input power up to 5W. It provides very low insertion loss (0.5 dB typ.) as well as low typical phase unbalance (7˚) and amplitude unbalance (0.2 dB). Featuring core and wire construction mounted on a printed laminate base with wraparound terminations, the unit comes enclosed in a miniature, shielded package measuring just 0.43 x 0.69 x 0.42”, ideal for dense circuit board layouts.


• high power input, 5 Watt max. • wide bandwidth, 440 MHz • good amplitude unbalance, 0.2 dB typ. at 1 dB bandwidth • excellent phase unbalance 7 deg. typ. at 1 dB bandwidth
