Down-conversion mixer
http://rfic.eecs.berkeley.edu/~niknejad/ee142_fa05lects/pdf/lect15.pdf Digital down-conversion is a digital-signal-processing technique that is widely used in digital radio receivers. This article will review the basics of a digital down-converter (DDC). We’ll first look at the advantages of using a DDC rather than its analog counterpart. Then, we’ll discuss an example and explore … See more In the receiver of Figure 1, the first bandpass filter, BPF1, performs image rejection for the first mixer, labeled “RF Mixer” in the figure. It … See more We can consider three main limitations of the dual-down-conversion receiver shown in Figure 1: 1. The two baseband paths must be highly … See more In this article, we examined the benefits of using a DDC. We saw that a DDC can improve the performance of the basic dual-down-conversion receiver: It can eliminate imbalance … See more Let’s assume that after analog-to-digital conversion the spectrum of the desired signal is as shown in Figure 4. The desired signal is centered at 110 MHz, and it has a bandwidth of 4 MHz … See more
