Hi group, Just playing around in KiCAD: This software is new to me. I normally use something else. 100mm x 100mm board, no case. Which injectors are the most useful? Regards, Jay_Diddy_B |

Hi Jay_Diddy_B Thank you for your efforts personally I would interested in all of them however the Picotest J2120A Line Injector would be a great place to start |

It is also difficult to see the part number on the SOIC8 - I want to recall it was an op-amp of some kind. --- End quote --- The pictures that were included are actually the J2111A I was having difficulty getting the component values, that I can read in the photograph, in the model agree with the datasheet performance. This are the specifications: LTspice model J2111A And the modelling results: I have attached the LTspice model. Regards, Jay_Diddy_B J2111A concept model.asc (5.46 kB - downloaded 143 times.) |

This what I have come up with for the 2120A: I am showing the IRF540, but the plan is to use the AOT2618. The artwork is single-sided: The board is 100mm x 100mm The plan is to use Keystone 575-4 for the connections. Comments? Jay_Diddy_B |
