SFP-04312-SB is a WR-04 X3 passive multiplier that utilizes GaAs Schottky diodes to generate third order harmonics with good harmonic and fundamental suppression. This multiplier requires an input frequency range of 56.67 to 86.67 GHz at +20 dBm RF power to yield typical 0 dBm output power at 170 to 260 GHz. The multiplier is equipped with a WR-12 waveguide and UG-387/U-M flange as its input port and a WR-04 waveguide and UG-387/U-M flange as its output port.
