Abstract(in English) | This paper presents the development of V-band planar Gunn VCO using no novel flip-chip GaAs Gunn diodes and varactors mounted on aluminum nitride (AIN) substrates. Due to using flip-chip bonding technology and unpackaged Gunn diodes, the Gunn Oscillator can be expected to realize low-cost mass production. A varactor tunable Gunn VCO shows a tuning range of over 450MHz at a center fiequency of 60.14GHz. The output power is on the average 34.8mW and shows a variation of less than 0.15dB. An excellent phase noise of -81,3dBc/Hz at 100kHz off carrier has been achieved. To overcome thermal limitations of the Gunn VCO, the thermal characteristics of flip-chip Gunn diodes mounted on AIN substrates have been calculated. We obtain the maximum thermal resistance of 35.4℃/W, which is comparable to a value from a conventional Gunn diode mounted on a diamond heat sink. |
