Abstract: In this paper, a design of Beidou radio-frequency integrated module is discussed in detail. In order to minimize thevolume of Beidou user equipment, the size of the new module is only 65mm×55mm×16mm by getting the lower-noise- amplifiermodule, the modulation-demodulation module and the power-amplifier module in the primal communication system together. In thedesign, a scheme of direct down conversion to demodulation is presented. And the miniaturization of the module is realization, by asmart design of the structure. All the test results meet the Beidou terminal specification. This module can be widely used in theBeidou user equipment.
