60-GHz-band MHMIC Frequency Multiplier Module for Multi-port Interferometer Receivers

In this paper, a 60-GHz-band miniaturized LO frequency multiplier module is presented. The ×4 frequency multiplier is appropriately designed as a LO chain to cover the entire band and provide enough power for mm-wave multiport receivers. To obtain a high suppression harmonic parameter, two compact bandpass filters are designed and placed after each multiplier. The miniaturized module with competitive parameters is fabricated and tested successfully through an MHMIC structure layout design.
