Hi Guys, Anyone know what transistor this is :SOT23 marked S4. It's at the front end of a 433MHz receiver which I'm trying to figure out. It's followed by another SOT23 P2p which I've identified as a BFR92A I can't track down the S4 - so any help/advice would be good. Thanks, John *************************************************************** John.Walshe@inpactmicro.com INPACT MICROELECTRONICS (Irl) Ltd 21A Pouladuff Road, Cork, Ireland, Tel: +353 21 4318296 Fax: +353 21 4318980 WWW.INPACTMICRO.COM *************************************************************** -- http://www.piclist.com hint: The PICList is archived three different ways.
