I'm looking for a chip with the body marking: 31135. Anyone know this chip and who make it? It's a narrow band FM receiver. I have one piece used in a cheap HAM radio. I guess it is of a chinese/taiwanese origin. Any help would be much appreciated.

Are you sure that this is a 31135 and not a 13135? MC13135 is a dual conversion IF chip primarily for FM use (but could be used for other receivers). It was made by Motorola but is discontinued. You can still find suppliers around. Do a Google search and you'll find all the info you need. Hope that helps.
 

Found it already. It's a japanese clone. Thanks
