SFP-05210-SB is a WR-05 X2 passive multiplier that generates second order harmonics with good harmonic and fundamental suppression. This multiplier requires an input frequency range of 70 to 110 GHz at +17 dBm RF power to yield typical +5 dBm output power at 140 to 220 GHz. The multiplier is equipped with a WR-10 waveguide and UG-387/U-M Anti-Cocking flange as its input port and a WR-05 waveguide and UG-387/U-M Anti-Cocking flange as its output port.
