Analysis of System Parameters of a Six-Port Communications Receiver with Analog I/Q Regeneration

In this paper system level parameters for the compression behavior as well as second and third order distortions of a six-port communications receiver with analog I/Q regeneration are determined by system simulations. The parameter values are qualified for a range of local oscillator (LO) signal powers. A recommendation for a well-suited LO signal power is derived from the resulting parameter plot. The recommended LO signal power is supported by investigation of the receiver´s conversion efficiency. The results are also valid for other ways of I/Q regeneration based on passive mixing.
