Mini-Circuits’ SCTX4-52HP-20W+ is a high-power, surface-mount transformer with a secondary/primary impedance ratio of 1:4, covering the 30 to 512 MHz band. The transformer is capable of handling RF input power up to 20W across entire bandwidth. It provides low insertion loss (0.3 dB) as well as good matching VSWR 1.10:1. Featuring core and wire con- struction 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.
