A varactor tuned low-cost 24 GHz harmonic VCO
Fachgebiet Höchstfrequenztechnik, Technische Universität München, 80290 München, Germany
Abstract. We present a low-cost 24 GHz VCO that is based on a microstrip design combined with discrete packaged devices. The output frequency is generated by a harmonic oscillator. The tunabilty was reached using a varactor diode. Two versions of the VCO were built, one has a wide tuning range of 1.1 GHz and the other one has a high output power of 3.7 dBm.
