Design of Phase Quantization Digital Radio Frequency Memories

摘要

This paper discusses the designs of the resistor loop phase shifter,inputencoder, and output decoder used in a phase quantization digital radio frequency memories (DRFM), and analyzes the relationship between instantaneous bandwidth and sampling frequency of the phase quantization DRFM. The results show that the instantaneous bandwidth of the phase quantization DRFM is equal to, in numeral. the sampling frequency, which is the same as the I, Q double channel amplitude quantization DRFM.
