Hi all, i need to know that which chip can i use to amplify a signal of 16.6MHz???? i used this IC called LF357 which has a bandwidth of 20MHz.... its supposed to amplify a signal of 16MHz....
it did amplify the signal bt reduced the signals freq to almost like 7MHz which i'm unable to understand why..... i used the schematic attached..... the input was a 1.4V, 16MHz sine wave which was clamped to 1V.... meaning the lower peak was at 1V and the upper peak was at 2.4V
so i wz wondering where the problem lies.... like is there any problem with the design or is the IC unable to deal with the freq??? plz suggest something....
incase the IC is incapable then do suggest me a few part numbers that are most likely to be found in the local market.... as i live in Pakistan.... the part numbers that are used in VCRs, Cassette Players are easily available and the stuff that isnt used in these items is hard to find....
