Under the Hood: Silicon TV tuners clearing hurdles

This article is a little bit dated but I just read through it and thought it was kind of interesting.  It describes some of the challanges that were faced when changing over from a can tuner to a silicon tuner.  It’s a little technical, but I found it interesting.

The primary technical differences in tuner design considerations between mobile phone applications and broadcast TV are bandwidth, interference and dynamic range. A cellular receiver has to function over a very narrow range of frequencies. For instance, a typical GSM receiver needs to cover only 25 or 30 MHz, whereas a TV tuner must receive more than 800 MHz of bandwidth (from 42 to 864 MHz).
