Find the third-order intercept points for the problem of Example 10.4 when the positions of the amplifier and mixer are reversed.
Example 10.4 If the intermodulation products from each stage have relatively random phases, which may occur when the intermodulation products are not very close to the fundamental signals, it may be proper to treat the individual contributions as incoherent, allowing us to add powers. It is straightforward to show that the overall intercept point in this case is given by
