Abstract
In this chapter, a few important non-idealities of a multiplexing phased-array architecture are discussed. Section 6.1 discusses the angle deviation from the expected viewing angle due to the finite analog filter bandwidth. Section 6.2 presents the influence of non-ideal switches on the array pattern. Section 6.3 discusses the noise performance in a sampling environment. Section 6.4 discusses the impact of adjacent channel interference. Section 6.5 presents simulation results of the multiplexing architecture. Section 6.6 shows the signal, noise and distortion power flow diagram of a multiplexing architecture, which is the realization of the generalized phased-array model presented in Sects. 3.6 and 6.7 concludes what has been discussed in this chapter. Non-idealities like timing jitter impact and isolation between switch paths are not discussed in this chapter. They are recommended for future works.
