Publication number: 20150139047Abstract: An entire radio transceiver can be easily integrated into one IC chip. In order to integrate the IF filters on the chip, a heterodyne architecture with a low IF is used. A single, directly modulated VCO is used for both up-conversion during transmission, and down-conversion during reception. Bond-wires are used as resonators in the oscillator tank for the VCO. A TDD scheme is used in the air interface to eliminate cross-talk or leakage. A Gaussian-shaped binary FSK modulation scheme is used to provide a number of other implementation advantages.Type: ApplicationFiled: December 22, 2014Publication date: May 21, 2015Inventors: Karl Håkan Torbjörn GÄRDENFORS, Sven MATTISSON, Jacobus Cornelis HAARTSEN
