Abstract :
A 38 GHz coplanar 8th harmonic mixer operating as a down converter on high resistivity FZ (float zone) silicon is realized. Two aluminum metal layers are used. Instead of air bridges, MIM (metal insulator metal) connections between the ground planes are used. The harmonic mixer was realized as a single balanced mixer with two flip chip bonded double Schottky diodes. The mixer works at the 8th harmonic frequency of the LO signal (4.6 GHz). With an RF frequency of 38 GHz this leads to an IF frequency of 1.2 GHz. A minimal conversion loss of 23 dB for a LO power about 20 dBm was achieved.
