Abstract

In a satellite communication system, for the design of receiver system. Since the characteristics of the system, we need to reduce the IF down converters count on the ground communication central station, expand the dynamic range of receiving system to make full use of satellite transponder resources. ATMega128 is used as a programmable controller, ADF4360-8 generates the local oscillator signal source, AD8343 chip is used as a frequency mixer and AD8367 is used as a VGA controller chip, which constitutes the logical architecture. We design and implement a low-distortion broadband IF down converter with multi-purpose in time division, flexible and convenient operation features.
