Abstract:

In this paper, a K-band four-channel integrated receiving front-end module is developed using the multilayer low temperature co-fired ceramics (LTCC) technology for the application of low earth orbit satellite communication. The operating frequency is from 17.7 to 20.2 GHz. MMIC chips, including low noise amplifiers, 6 bit phase shifters, 5 bit attenuators and series-parallel converters, and multilayer ceramic capacitors are mounted inside the cavity of the module while passive components, such as a power combiner and low-pass filters, are embedded into the multilayer substrate. The overall size of the module is 28×28×1.35 mm³. In measurements, the in-band channel gain is over 31.5 dB, the noise figure is 1.7~1.9 dB, and the suppression against the transmitting band of 28~30 GHz is over 61.5 dBc. The control errors of phase shift and attenuation amplitude are better than 4.7° and 1 dB, respectively. It is demonstrated that our design has the advantages of high integration, high gain, high suppression and low noise.

Key words: low temperature co-fired ceramic(LTCC) technology, integrated receiving front-end module, low earth orbit(LEO) satellite communication
