- Abstract:
- An efficient way to design a down-converter assembly for the Ka-band millimeter system is presented, in which dielectric resonators(DR’s)are adopted in the Schottky barrier diode image recovery mixer and the local oscillator(LO).DR structures guarantee high frequency stability with an acceptable volume.The configurations of low noise amplifier, mixer and oscillator in the assembly are described and fabricated to estimate the chain performance.According to the verification results, the assembly exhibits the noise figure of less than 5 dB over 1 GHz frequency range, and the single-sideband phase noise(200 kHz offset from carrier frequency)of -70 dBc/Hz.Utilizing the DR structure, the frequency stability of the local oscillator is less than 60×10-6/℃.
