| Abstract | Heterodyne mixers with a micromachined horn antenna and a SIS tunnel junction as mixing element are tested in the 75-115 GHz and 180-220 GHz frequency range. The mixer performance is optimized by using a backing plane behind the dipole antenna to tune out the capacitance of the tunnel junction. For the W-band mixer a lowest DSB receiver noise temperature of 30 /- 3 K is measured at 106 GHz with a 3-dB bandwidth of 8 GHz. Preliminary measurements of the 180-220 GHz mixer yield a 109 K DSB noise temperature at 204 GHz. The design of a micromachined 190 GHz SlS focal plane array is described |
