4 turns input 5 turns output
Used material: 1 core of 73 material Fair-Rite 2873000202
Input = 4 turns / Output = 5 turns
4 square = 16 / 5 square = 25
25 / 16 = 1.56
When Input impedance = 50 Ohms,
Output impedance wil be 1.56 x 50 Ohm = 78 Ohms
Optimization for 7 MHZ:
2 X 39 pF in parallel
Optimization for the entire frequency band with 39 pF:
Insertion loss:
Insertion loss for 2 devices:
@ 7 MHz loss of one device = 0,16 dB.
