  • PRINTED CIRCUIT BOARD WITH ELECTROMAGNETIC BANDGAP STRUCTURE FOR LAUNCHER IN PACKAGE DEVICES
    Publication number: 20240196520
    Abstract: A Launcher in Package (LiP) device for wireless communications, e.g., radar communications at 77 GHz, includes a printed circuit board (PCB) arranged between a radio frequency (RF) chip package and a radiating antenna structure. The PCB include an electromagnetic bandgap (EBG) structure including a plurality of EBG elements printed in a periodic pattern on the side of the PCB facing the radiating antenna structure. The plurality of EBG elements border at least one side of an RF channel through the PCB that couples an antenna element of the radiating antenna structure with a corresponding RF launcher in the RF chip package.

  • Voltage controlled oscillator (VCO) with simultaneous switching of frequency band, oscillation core and varactor size
    Patent number: 8120440
    Abstract: The invention relates to a voltage controlled oscillator for generating a variable frequency. The oscillator comprises an oscillator core and a transconductive portion for compensating current losses in the oscillator core. The oscillator core comprises an inductive portion with at least one inductive element and a capacitive portion whose capacitance can be continuously varied by means of a control voltage for varying said frequency. The capacitive portion comprises multiple variable capacitive elements whose capacitance is continuously variable by means of said control voltage, each variable capacitive element being switchable for being added to or removed from the capacitive portion.
