In this paper, a novel model for accurately evaluating the performance behaviour of subharmonic self-oscillating mixers (SOM) is presented. This model permits to investigate on the effects of various design parameters of SOMs namely in terms of conversion gain, IF frequency, noise figure, and intermodulation distortion. Such an accurate model is specifically important in the design of millimeter-wave...
In this paper, a third and fourth harmonic FET self-oscillating mixer (SOM) operating at 5.8 GHz and 7.6 GHz, respectively, with high measured conversion gain (8.75 dB) is presented for the first time to the authors' knowledge. The proposed structure is fully balanced to provide inherent RF-LO isolation and suppression of harmonics and AM noise, but it does not require complex and space-intensive...
Self-oscillating mixers (SOMs) are an excellent choice for low-cost modern receiver architectures, because both the oscillating source and the mixer are combined in one single device. Moreover, subharmonic operation reduces LO frequency requirements and therefore provides a very good choice for millimeter-wave systems. In this paper, a fully-balanced SOM structure at high harmonics with high conversion...
