Receiver Dynamic Range: Part 2
Part 1 of this article reviews receiver measurements which, taken as a group, describe receiver dynamic range. Part 2 introduces comprehensive measurements that attempt to characterize a receiver’s dynamic range as a single number. the receiver can process acceptably. In simplest terms, it is the difference in dB between the inband 1-dB compression point and the minimum-receivable signal level. The compression point is obvious enough; however, the minimum-receivable signal must be identified. There are a number of candidates for minimum-receivable signal level, including: “minimum-discernable signal” (MDS), tangential sensitivity, 10-dB SNR, and receiver noise floor. Both MDS and tangential sensiti
