In this paper we will present our latest research results of integrated silicon antennas for automotive radar applications (f = 80 GHz). The design procedure as well as simulation and first measurement results will be given. Within this work two antenna designs, a 1-dimensional array (single line antenna) and a 2-dimensional antenna array (4 lines with 4 patches), will be shown. First measurement...
Monolithic integrated IMPATT diodes are combined with coplanar waveguide resonator on unthinned silicon wafers to form simple oscillators for mm-wave operation (around 90 GHz). This paper describes properties of planar IMPATTs, their integration into SIMMWICs and proves their basics functionality as mW power sources for simple cost effective and flexible mm-wave systems.
Ge-pin-photodiodes monolithically integrated on strain-relaxed buffers are presented. For easy on-wafer testing mesa-type photodiodes are designed for vertical light incidence. At the telecommunication wavelengths of 850 nm, 1298 nm and 1550 nm zero-bias external quantum efficiencies of 23%, 16% and 2.8% are measured. An optoelectronic 3 dB-bandwidth, limited by the RC-product, has been measured up...
