The Design of Leadless TTD TR Module with High Integration

This paper proposes a true time delay (TTD) transmit-receive module (TRM) with high integration, which can improve the bandwidth of active phased array radar (APAR) effectively. This TRM adopts leadless system-in-package (SIP) structure, realizing all 3-D interconnection from components, board to module level and achieving high integration, miniaturization and lightweight. With co-simulation of field and circuit, this TRM is designed and developed. The measurement results show good performance. Moreover, this module has good adaptability to environment and engineering significance. This method can be extended and applied to S to Ka band.
