Baras, TorbenTorbenBarasJacob, ArneArneJacob2021-11-042021-11-042008-06IEEE MTT-S International Microwave Symposium Digest (): 4633177 359-362 (2008)http://hdl.handle.net/11420/10788A fully integrated K-band voltage controlled oscillator module is presented. The design is realized in low temperature co-fired ceramics, making extensively use of the multilayer features and advanced capabilities of this substrate system. The interior packaging technology exclusively utilizes flip-chip mounting of bare semiconductors. As a key element, a varactor-tuned substrate-integrated-waveguide resonator and the associated design constraints are presented. The hybrid oscillator is integrated in a hermetic surface mount package of 8 mm × 12.5 mm, achieving an output power of more than 6 dBm in a tuning range between 19.58 GHz - 20.2 GHz. The measured phase noise is -118 dBc/Hz at 1 MHz offset, a figure-of-merit of -184.7 dB for this design. © 2008 IEEE.enTechnikIngenieurwissenschaftenConference Paper10.1109/MWSYM.2008.4633177Other
