An X-Band SiGe Single-MMIC Transmit / Receive Module for Radar Applications

The development of a single-MMIC transmit/receive (T/R) module for radar applications is described. The T/R module is fabricated in the IBM 8HP SiGe BiCMOS process technology. The topology of the T/R module is described. The performance of the underlying RF components is shown, including LNA, SP2T switches, SP3T switches, phase shifters, and power amplifiers, all with simulated and measured performance results. The simulated performance of the complete T/R module is presented, as well as the MMIC layout. The applicability to various radar systems and concepts is discussed. It is shown that the RF performance and the low power consumption of the device make it attractive for the described applications.
