  • A multilayer front-end for an imaging radar sensor
    Abstract — In this contribution a compact multilayer front-end for a 24 GHz FM - CW imaging radar sensor is presented. Key structures of the multilayer printed circuit board (PCB) design are the contacting areas of MMICs, space …
  • A fully-monolithic SiGe-BiCMOS transceiver chip for 24 GHz applications
    The paper presents a fully integrated transceiver circuit consists of a VCO, a frequency divider. a phase-frequency detector and a mixer based on SiGe- BiCMOS technology for 24 GHz application on one chip. Figure I : Transceiver chip in a FM - CW radar system .
  • Integrated stacked patch antenna array on LTCC material operating at 24 GHz [automotive radar applications]
    Abstract: This paper presents the concept, design and measurement results of a broadband stacked patch antenna array integrated within an FM - CW radar module, realised in LTCC (Low Temperature Cofired Ceramics) technology, for automotive applications operating at 24 GHz . … its flexibility in realising an arbitrary number of layers with easy-to-integrate circuit components like thick …
  • RADAR flashlight for through-the-wall detection of humans
    … used with the laboratory prototype is shown in Figure 2 as the printed circuit board to the … The laboratory prototype unit shown in Figure 2 operates on a frequency near 1 0.525 GHz , although an earlier version of the system was operated at 24 . The current laboratory prototype is a homodyne radar configuration, although a frequency modulated continuous wave ( FM - CW ) system could be used for applications where information is required to determine the range to the target.

  • Helping Receivers Mature At GEC's HRC | Components content from Microwaves & RF
    Microstrip circuits on Z-cut quartz substrate (26 x 24 x 0.125 mm) included E-plane probe waveguide-to-microstrip transitions, which formed hermetically sealed waveguide windows when the substrate ground plane was soldered to the box package. This may best be demonstrated by a 94- GHz FM - CW transceiver contained within a volume of about 1 cubic inch26 and a 94-GHz dual-channel radar receiver/duplexer with a high level of integration.
  • Design and Technology of Microwave and Millimeterwave LTCC Circuits and Systems
    Layout of the FM - CW radar module with integrated stacked patch antenna array on the top and the frontend on the bottom. The antenna has to comply with the following specifications: The operation frequency range is defined by a centre frequency of 24 GHz , with a bandwidth of at least 2 GHz. The bottom side of the ceramic block carries the RF front-end circuits and components.
