The 19HD358 from Smith Interconnect is a Space-qualified Isolator that operates from 17.3 to 21.2 GHz. It can handle a CW input power of 20 W, provides more than 21 dB of isolation, and has an insertion loss of less than 0.2 dB. This isolator has completed qualification for spacecraft using Smith Interconnect’s comprehensive in-house test facilities that comprise sine and random vibration, mechanical shock and RF power TVAC, average power and multipaction, and critical power testing. It is available in a module with a WR51 waveguide interface and is designed to be used on the output of a TWTA employed in the transmission network of a GEO/MEO payload.
