Design of an eight-hole directional coupler for W-band cryogenic receivers

For the system noise temperature calibration of the K/Q/W triple-band cryogenic receiver on Tianma Radio Telescope (TMRT), a design of W-band eight-hole waveguide directional coupler is proposed in this paper. Based on the hole coupling principle proposed by Gian Guido Gentili, a simulation model of...
