Abstract:

This paper presents a design of X-band transmit system by synthesizing transmit modules on background of active phased array radar application,with each transmitting module as one channel.The designed modules are completed by MMIC and MCM technology.Output power of the substrate array is more than 80W,and the amplitude imbalance is lower than 0.5 dB.The array has the advantages of small shape,high output power,high reliability and good consistency in continuous wave.
