Abstract

Circuit topology Frequency Mixers MMICs Oscillators Phase noise Resonance RLC circuits Signal design UHF circuits
This paper presents experimental results of an extremely low power consuming hybrid push-pull self-oscillating mixer (SOM) circuit at UHF band. The SOM is designed and fabricated using matched pair Si BJTs and high Q resonators. Measured phase noise of the free-running voltage controlled oscillator is -76.5 dBc/Hz at 10 KHz offset; a 20 dB upconversion gain is also measured for the mixer.
