Mini-Circuits’ SCTX4-32HP-20W+ is a high-power, surface-mount transformer with a secondary/primary impedance ratio of 1:4, covering the 1.0 to 320 MHz band. DC current pass IN to OUT, the transformer is capable of handling RF input power up to 20W. It provides low insertion loss (0.3 dB) as well as good matching VSWR 1.10:1. Featuring core and wire construction mounted on PCB, the unit comes enclosed in a miniature, shielded package measuring just 0.50 x 0.50 x 0.20″, ideal for dense circuit board layouts.
