Abstract The principle of multi-bit Phase Quantization Digital RF Memory (PQDRFM) and the implementation of Phase Quantizer (PQ) are discussed. The topology of PQ which is easy to monolithic integration is given. The factors affecting the spurious level of PQDRFM are investigated and the expression of the relationship of spurious level via the quantization bit number is given. The emphasis is put on the effect of the unbalance of PQ input amplitude and phase on the spurious level.

Key words： Digital RF memory Phase quantization Spurious level
