    <title language="eng">A new design approach for low phase-noise reflection-type MMIC oscillators</title>
    <abstract language="eng">In this paper, optimization of the loaded quality factor Q&lt;sub&gt;L&lt;/sub&gt; for reflection-type heterojunction bipolar transistor (HBT) oscillators is investigated. The main result is an optimum relation between the S-parameter phases at the three transistor ports. A new design strategy for this type of oscillator is proposed. The analysis is verified by comparing several Ka-band monolithic-microwave integrated-circuit oscillators in GaAs HBT technology with different resonators. The measured loaded Q&lt;sub&gt;L&lt;/sub&gt; values correspond to the measured phase noise of the circuits. At an oscillation frequency of 33 GHz, an excellent phase noise of -87 dBc/Hz at 100-kHz offset frequency is achieved over the whole tuning range.</abstract>
