摘要：

A simple low-cost and high-performance 22 GHz band down-converter is developed for a future direct-to-home satellite broadcasting system. The down-converter consists of a low-noise HEMT preamplifier, an image recovery mixer with a novel structure using dielectric resonator filters, a 21.4 GHz GaAs FET oscillator stabilized by a dielectric resonator, and an IF amplifier. These components are fully integrated using MIC technology into a small size. A total noise figure of less than 2.8 dB is obtained over the 22.5-23.0 GHz frequency range. The local oscillator achieves a frequency variation of less than 600 kHz(p-p) over a temperature range of -20-degrees to +60-degrees-C.
