at those frequencies, the bond wires are way too long. You have to do all u can to reduce the length of the bond wires. I would then use very soft gold ribbon, and laying it flat on the board (no loop height) bond the 3 ribbons. by using 3 ribbons, and positioning them carefully, you will better approximate a transmission line impedance as opposed to just a wire loop with parasitic inductance.
Finally, on the right of your drawing, you show 2 monster sized square pads, but no details on what they are. Are the connected thru via holes to a back side? If not, those pads LxW are probably resonant at 145 GHz, and need to be made much smaller.
