WebAn IF-based receiver is known as a heterodyne receiver. The use of an IF simplifies the design of tunable receivers and reduces the number of components that must be compatible with high frequencies. IF … Web1. An IF of zero has a few disadvantages: the image overlaps your signal, which is fine for AM but not much else. You can use a second ADC for the Q signal, where the last downmix is done with an LO output at a 90 degree offset, but at this point you are effectively building a direct-conversion receiver anyway.
