i understand and appreciate your concern; however, i am not an amateur to electrical engineering. I have a B.S.E.E. , but I have never built an amplifier before and would like to get into it. I have the knowledege of Electromagnetics, Antennas, etc to be able to work on a design and understand it. I...

efficient, low cost, high gain rf cellular power amplifer
hi, I am looking to design an efficient, low cost, high gain dual band rf cellular power amplifer. does anyone have any schematics they have used in the past? any good antenna designs if any, etc? maybe i should use a class A amplifier with two diplexers and a lot of filtering? what are your thought...

high accuracy self calibrating temperature logger
hi guys, what is the cheapest way to design a high accuracy self calibrating temperature logger? Could I use opamps and maybe 2 RTDs to achieve this? The recording temperature range is -40F to 112F...what do you guys think? I appreciate your help in advance. are there any micros out there that can m...
