Homer's receiver design requirements are to: 

1-attenuate all Murphy signals baby at least 50 dB 

2- Use as low an IF center frequency as possible 

determine the value of IF center frequency f_o ^IF  in Homer's design 

eecs 622 exam II f17.doc 12/4/2017 Problem 2 - 15 Points Homer has designed another excellent mixer. It generates just one 2nd-order product at the mixer IF port: fif = fio + FRE Homer is using this mixer in a receiver he is designing. Homer will use this receiver to listen to his very favorite radio station: a station transmitting at 1.0 GHz. Homer uses his mixer's 2nd-order term to up-convert to an IF center frequency (i.e., FF >1GHz ). Homer's excellent mixer does not generate any other 2nd-order products, nor does it generate any 1st or 3rd order products (none- absolutely none!). However, Homer's mixer does create this (but only this!) spurious 4th. order product at the mixer IF port: FIF FRF - 3410 Because of this product, Homer must use a preselector filter in his design. This preselector filter: 1. has a very narrow bandwidth, centered at 1.0 GHz, and 2. attenuates all signals with a frequency greater than 6.0 GHz by 50 dB or more.
