Consider Overall Cascaded Performance When Comparing Integrated RF Frequency Mixers to Passive Mixer Solutions
The following application note compares the features of an integrated RF and passive mixer solution. It discusses the main features of both solutions and shows the main advantages of an integrated over a passive solution.
In the past, RF designers have used passive down-conversion mixers to obtain the best overall linearity and spurious performance for their high performance receiver designs. There are several disadvantages when using discrete passive mixers in these designs. Passive mixers have insertion loss
