The Design of LTCC-based Miniaturized X-band T/R Module

Active phased array radar is widely used in radar systems and electronic warfare. T/R module is one of the key components in the active phased array radar system. This paper takes advantage of high integration of LTCC technology to design an X-band four-channel miniaturized T/R module. This module adopts high-integrated technologies such as MCM and MMIC to integrate microwave circuits into multi-layer LTCC substrates. Finally, the designed and implemented T/R module has a volume of 46.35 mm $\times 59.2$ mm $\times 9.7$ mm, its transmit output power is greater than 46 dBm, its receive gain is better than 20 dB, and the noise figure is under 2.3 dB. This module has good performance and high engineering practical values.
