Abstract :
In this paper a Ka-Band oscillator exhibiting single sideband phase noise below -150 dBc/Hz at 10 MHz offset from the carrier is described. The oscillating frequency in the range 26-40 GHz is determined by the dimensions of an externally attached cavity. All electronic components including the MMICs are placed on a low temperature cofired ceramic (LTCC) substrate. A metallised liquid crystal polymer (LCP) cover is soldered on the substrate, thus providing a hermetic sealing of the millimetre wave MMICs.
