1 RF Components & Circuits VE3KL Session 1 Ferrite and Powdered Iron Toroids Transformer, SWR Bridge, Low-Pass Filter Ferrite SWR Bridge Kit Kits and Parts FT :1 Transformer Ferrite

2 Low-Pass Filter… Powdered Iron Cores T50-6 Two T50-6 Toroids 9 and 8 Turns 9 Turns #248 Turns #24 Input Output 9 Turns8 Turns Circuit Board and BNC Connectors in Kit

3 Hardware Tools Required Very Important With new blades Plus a small vice, optical magnifier, laptop PC 60 Watts

4 Software Tools & Links : Free Filter Design Software Elsie: Zplots: (Optional: uses Excel) Can use VE3KL Software Kits and Parts for SWR Kit Manual and Data Sheets, Download the Toroid Calculator (include VB6 Runtime) Look under Toroids button

5 Materials Selection T50-6 Powdered Iron FT50-43 Ferrite High Q Coils/Resonators Band Pass Filters Low Loss Transformers Transmission Line Transformers EMI Filters

6 T50-6 Powdered Iron Core

7 Inductance Formula L = A L *N 2 /1000 uH N = nr. of Turns A L = 4 for T50-6 Iron Powder Core A L = 440 for FT50-43 Ferrite Core These numbers from Micrometals Data Sheet

8 Fair-Rite 43 Material

9 Micrometals Powdered Iron Cores

10 FT & T Turns, 9 Inches: 9 Turns 10 Inches Measure L {Low Frequency with L/C Meter} Ferrite Iron Make 1 ferrite coil (9 Turns) Make 2 powdered iron coils (8T and 9T) Check Measurements against Formula Record data for filter design

11 End of Session 1 Ferrite Iron Clockwise
