Abstract

This paper presents theoretical and experimental results of a low-power-consuming hybrid push-pull self-oscillating mixer (SOM) circuit at the UHF frequency band. The frequency-stable SOM circuit is designed and fabricated using matched-pair Si bipolar junction transistors and high-Q resonators, where measured phase noise of this free-running voltage-controlled oscillator is -101.2 dBc/Hz at 100-kHz offset. A 20-dB up-conversion gain, a compression dynamic range (CDR) of 65 dB·MHz, and a spurious-free dynamic range of 50 dB·MHz ^2/3 are also measured for the mixer portion of this SOM. Moreover, a down-conversion gain of ≈-2 dB with a CDR of 100 dB·MHz is also measured
