© 2019 IEEE. Technologies and topologies used in the design and fabrication of high power amplifiers are considered deciding factor in the size, cost and performance of Transmit / Receive modules (TRMs) of modern Active Electronically Scanned Array (AESA) radar. In this paper, a survey of contemporary semiconductor technologies like Si, SiC, GaAs, GaN, SiGe and InP for the design and fabrication of transmit path of TRM has been presented. TRM architectures and packaging technologies are also reviewed in terms of ease of implementation with optimum outcome. GaN MMIC has been found as the latest trending technology for TRM transmit path due to higher power densities, reliability, lower cost per watt production, and higher efficiencies with ease of implementation. Multiple MMICs integrated in suitable packaging technology-based hybrid approach has been found as one of the cost-effective solutions with high end results in the design of TRM.
