An ultra-wideband power divider with out-of-band filtering and DC blocking functions is presented. The divider consists of three parallel-coupled lines, a short-circuited shunt stub and a resistor. The divider was implemented in a two-layer printed circuit board with a high dielectric constant. The measurements show a minimum insertion loss of −0.4 dB in the middle band and a rejection of −17 to −18 dBc at 1.5 and 11.5 GHz, respectively.
